Dear GretchKen Industries, Inc.,
We love the booths we purchased from you last spring. They serve a great purpose of connecting Southern California’s blind and visually impaired patrons of the Braille Institute award winning Library to the world around them. These booths are used daily to record national and local news, and numerous other publications. Over 10,000 patrons listen to the recordings using their phones, our website (www.telephonereadernews.org), or their smartphones.
GretchKen Industries were patient and professional with our budgetary process. They arrived intact and were easy to assemble. The booths are well-made and have greatly improved the quality of our audio recordings as well as provided pleasant and comfortable reading and recording environment for our dedicated volunteers.

I bought a custom made GretchKen booth about 5 years ago to put in the back bedroom of my motorhome. I had removed the existing bed and moved a few things around to fit in the booth. It was stabilized with rods attached to the walls so that the booth wouldn’t move if I unexpectedly had to jam on my brakes when driving. I am thought to be the first voiceover to live, work, and travel fulltime in an RV. I spent months planning my booth size and dimensions, as well as trying to figure out mobile broadband and other possible issues that might arise on the road. I was a wreck when I first hit the road, not knowing if my setup would be quiet enough. I worried about highway noise when staying in parks close to interstates (to be honest, sometimes those places were just too loud, and the quietest booth on the world wouldn’t have helped). I worried about the rain (unless it was a hard, driving rain, it didn’t usually pose any problems). I worried a lot about my audio, because that’s my bread and butter. I sometimes didn’t tell clients that I was on the road, because I didn’t want them to have preconceived prejudices about my sound. (Sometimes if someone thinks you’re from a certain area, they “hear” an accent. I’ve had people think I was from the south and commented on my southern accent. I’m a New Englander, and, except for living for five years in Arizona, I’ve spent all of my life in there. No southern accent from this gal!)
My booth exceeded my expectations. I spent 19 months on the road, working fulltime as a voiceover. I narrated dozens of books during that time, voiced many radio and TV commercials, and completed extensive eLearning and recorded textbook projects. I now work out of my home studio in a somewhat larger GretchKen booth and still love the way my audio sounds with it. My motorhome booth has been disassembled and it stored in my basement, possibly awaiting a future travel situation.
Thank you GretchKen for the opportunity to express our appreciation for your excellent products. In 2009 we purchased your 8’x10’ sound enclosure and it has been in service ever since. It was surprisingly easy to put together and install. We had originally planned to build our own small studio. The local zoning and building codes would not allow that studio to be built without updating our entire building to current codes. We found that your “portable” construction enabled us to have the same size facility with no construction because the codes classified the booth as “portable furniture.”
Over the last six years our GretchKen studio has lived an exciting life as a voice studio, an audio and video editing facility as Framework Productions [an internet video producer], and currently our control center for “Christmas 1914.” This is a fourteen scene Christmas “walk-through” production depicting the lives of 3 war struck families, one German, one British, and one American. The “walk-through” takes seventy minutes to complete. Our cast and support crew numbers 250 individuals – all volunteers. Last year we held 8 performances and over 5,000 people came to see it.
The nerve center for this production is our GretchKen 8x10 sound booth. It gives our systems operators peace, quiet, and central air conditioning, which allows for clear focus on our operation. A single automation system [running all 14 scenes], and complete audio editing capability… all within our booth. A side feature of the booth is the large sound insulated window which allows us to give interested visitors an opportunity to watch our technical operation in action without disturbing the operators.
In the past six years we have not had a door squeak, a noisy lamp, or sign of deterioration of the acoustic foam. We were thrilled at the quality of the studio right off the truck – and we still are. Thanks for such a great product.
"We purchased these rugged custom sound enclosures to protect the operator's hearing from a 120dB alarm that is tested inside the enclosure and help reduce background noise in our factory. Gretchken designed these boxes to fit our safety and reliability needs and we have been very happy with them. That's why we ordered 7 of them!"
We took a few quick pictures of the booth - and I've included a fun little time-lapse video of it's construction.
The booth has been invaluable ot us in both our Radio and TV Production! Assembly was incredibly fast and easy, and the quality is fantastic. Thank you!

"When we purchased our 8' x 8' studio booth from GretchKen, we expected something great, and we got something amazing. This is by far the best investment I've made in my home (garage) recording studio since we built it. I was originally planning to use it for vocals, but we got the large one just in case, and it's a good thing we did. I record EVERYTHING inside the booth. Vocals, guitars, guitar amplifiers, drums, EVERYTHING. It's perfectly sized, perfectly deadened, and the input jacks have made for flawlessly efficient connections to my studio monitor controls as well as the in-booth headphones. Ultimately, we expected a 10/10, but we got 11/10. I can't recommend this company enough.
Thank you GretchKen. You've taken my home studio to the next level!"

I have had a 6x8 standard sound isolation booth from Gretch-Ken for over 5 years. I have used it regularly and found it to be well made, durable, very functional and perfect for my recording studio for voiceover, music and general audio production. A real value for the money!

I've had my soundproof booth for two years now. So keep in mind that I'm writing this in a state that's not "emotional because of something new." I've had it for a while and used it a lot, so it has been put to the test. It WROKS EXCELLENT for my needs.
"GretchKen provided the best and most cost-effective solution for installing a sound-proof booth inside our laboratory space. We have since had to move it to a new location and the ease with which it could be deconstructed and then rebuilt was only matched by the valuable after-service care GretchKen provided during that time"

We, at UITS IT Training & Education at Indiana University, love our new Gretch-Ken Industries sound isolation booth. I just spent the morning in our booth recording the audio for a departmental podcast that we put out each month. Yesterday, I spent several hours in the booth, capturing screen casts and adding voiceovers. Since my colleagues and I work in a large building with cubes, before we got our sound booth, it was difficult to find a place to record audio. Even if there was a conference room available, the humming sound of the fluorescent lights and A/C made it very difficult to capture high quality audio. We have had our sound booth now for almost 8 months, and we are extremely happy with it. It provides excellent noise reduction, and it is sturdy, pleasant looking, and comfortable. o:p>
My Booth from GretchKen has been great from day one. Not only does it do what I need it to do sound wise, but even in the Standard Model I have, there's room for a small table which holds my monitor. I couldn't deliever the audio quality I require without this booth! GretchKen also gets an A+ for customer service.
I am very pleased with my ISO booth. This booth sounds much less "boxy" than other ISO booths I have been in and the air management system is quieter and more effective than othe others. The ISO booth is very dry sounding unless you hang some hard stuff in it, but sometimes that is the best think, depending on your needs... Spend the little extra for added noise isolation options and you will be pleased with our purchase.

“We are very happy with the construction and the quality of materials. It's obvious you take pride in your work. Thank you very much. You might enjoy watching our "just for fun" time-laps video of the assembly.
Ken, Gretchen and Team,
I ordered a custom-sized "GK Professional Sound Isolation Booth" with the "Double Deluxe Upgrade" for in-home voice-over auditions. It's been one of the best purchases I've made in the past 10 years. Despite the small size I ordered, it never sounds like I'm recording in a tiny box thanks to the great materials it's constructed out of. I've seen my career take off now that I'm able to audition from home where I can take my time and really give my best performance. This booth rocks! Thanks, Gretch-Ken!
"I Love My Booth!!! You guys are the best!"
Scott Matthews Luth
"I record all my voice over work in my studio using the Stone Booth. It's a wonderful solution for someone who wants great sound and professional isolation without having to use a large booth. I prop it right on top of my desk in my office, and it works like a charm. I highly recommend it even for those who don't need to travel."
We ABSOLUTELY love, love, love our Booth! We use it ALL the time, and since having it, I don’t know how we ever functioned without it! We would recommend Gretch-Ken Industries to anyone!
The booth that we purchased from Gretch-Ken Industries works great! We now use the booth as a “multi-purpose” booth, for all kinds of testing.
Thanks Steve! We
proudly offer your booth design for sale to others.
I absolutely love my sound
isolation booth and it's exactly what I planed for!
We do all the audio production for Universal Studios Hollywood right here on the lot,
and we depend heavily on our isolation booth from Gretch-Ken. It's comfortable,
well-made and quiet. We even record our phone messages in it.
If you call Universal Studios for park information, you are listening to a Gretch-Ken booth!
Hope that helps!

The booth is everything I had
hoped and has created a really sane space in the vortex of NY.
The sound booth with faraday
cage that I bought from you all last year is working great for me.

"The people at GK Acoustics were great! They helped us determine our needs for our application and worked very closely with us throughout the entire process. We needed a quiet environment to test motors in an assembly line process. they helped design a booth that had the motor roll in for testing and then out for the next step of the process. the booth provided just what we needed. The assembly of the booth was also a breeze. We were able to assemble it easily within a day. We have no complaints with the product or the company and would gladly use GK Acoustics again if the need arise. Thanks GK Acoustics!

Just had to let you know that the
AudioGirls couldn't be happier with our sound booth.
Lori Rae Martin and Sylvia
Attached are digital pictures of
the two isolation booths that we purchased in early July 2003. I
have no idea where to even begin telling you how pleased and happy
we are with these booths. To begin with, assembly was a dream; we
had both booths uncrated and set up within about 2 hours. The
following day the sprinkler company installed the required-by-code
flexible sprinkler drops into each of the booths, and thankfully no
increase in outside sound was noted. The following day we moved our
custom built mixing stations up to the booths, installed 13" LCD
screens (to view the karaoke lyrics) and studio condenser
microphones and headphones, and gave everything a test run. WOW! The
quality of the vocals inside the booths was (and is) Amazing! Our
customers, who range from first time amateurs to aspiring stars,
can't get over the great sounding CD's they get after a recording
The Audio Video students here at
Alamogordo High School put in many hours in our new sound booth. Not
only did they assemble the entire booth on their own, but they have
recorded and mixed every AHS radio ad including PSA's inside the
booth. Thanks to members of our local media, our booth is equipped
with a mixing board, microphones, a computer with Adobe Audition
(audio editing software) and Frooty Loops (music maker software).
The sound booth allows me to teach in the classroom while work
continues in the booth - they can't hear me and I can't hear them.
The students have recorded PSA's on the importance of reading,
reporting date violence, drinking and driving, and others that have
been played on local radio stations. Recently, the AV students
completed a new DVD presentation for incoming Freshmen that
showcases various aspects of our high school.

“After determining our sound capture needs, we located Gretch-Ken Industries through a search of the Web for sound booths. Our multimedia experts were very pleased to learn that we could customize the layout of the sound booths without any additional costs. The sound booth assembly was quick and easy. Upon receiving two 4' x 6' booths, we were able to set them up the same day. We later added microphone arms and computer monitors to each booth, an additional customization that was very easy to accomplish. Our overall experience with Gretch-Ken was excellent.”Thanks,

We couldn't be more pleased with the booth. We were amazed at how solid the booth is considering how easy it was to put together. Every piece fit flawlessly and it's been in use since the day we set it up.
GK Acoustics worked with me
every step of the way to create; not only a completely custom sized
isolation booth to fit into the small space I had, but one that
looks, works and sounds great as well.
I've got a full blown Pro Tools
system and lots of gear set up in my
Well....WE LOVE IT!
Here's the report:
The thing arrived in fine shape. due to the fact that even the BUMS in NYC
are unionized, we had to uncrate it IN the truck outside the loading dock of
our building! No matter, we got it all in, THEN the fun began!
Partially cause we're idiots, and partially cause we were putting this in a
VERY tight space, the construction was not so smooth, but it IS mostly
our fault. Anyway, after getting an ex-football playing intern from one
of our clients to come up and help the two aging rockers (me + my bro),
we got it done. I was very impressed by the ease that things had
connecting once we got those corner braces in the right position.
The best thing is that I'm very happy we went with you guys.
We'd seen both your competitor's booths in different NYC
situations and were a bit unimpressed as to the amount of leakage
we heard. While none of these style booths are completely silent,
yours by far is the quietest! We figure this is due to the superior DOOR!
First thing we did with it was to record the vocals for the theme
of the new animated series coming in April on Comedy Central called
"SHORTIES". We're also doing a LOT of acoustic guitar recording in there
with a two mic setup. Sounds great!
The 6'x4' booth is also big enough to keep a 'half-stack' amp setup
in there and STILL be able to sit a guy down to record acoustic guitar
or winds, etc...
We started out doing most of our music "in the box", using samplers
and PODS. Having this booth means no more compromises!
Now then....the ONLY teensy gripe we have, and it aint a big one nor
unexpected, is the noise level of the cooling fan. While not horrendous,
it is a loud enough low hum to be too loud for any quiet recording
situations (vocals, acoustic guitar). I've heard and read similar gripes
with every other standard fan setup in these style booths so I was
kinda prepared. Having said that, the fan REALLY does move some
air in there!
That out of the way, we really LOVE the booth and feel secure we
went with the best company to build it! AND WE CAN TAKE IT WITH US!
