I have to use one of these booths at one of the places I mix at. Terrible! I finally found a sweet spot in the room, but its very small. I think its insulting to sell a room that purports to be a recording space and have to "doctor it up" with Auralex. I would ask them to fix the problem, or return it like a defective product. On the other hand, If you know the exact freq that is building up, try a Hemholtz resonator tuned tothat freq.

They are a total rip-off! Great if you like that phone booth effect!

The boot is too small! You need space to allow the vocals to bloom!

Depending on the material being sung, you may also need some space between your singer and the microphone as opposed to being tight all the time.

Don't bother buying any other foam or other crap for the booth. Just sell it!

The recording world is cruel.

I always found vocal booths to be very 'suffocating' for vocals. The confined space does not give them (vocals) room to breathe. That's why I opted for a silence case for my computer instead. Now I track vocals in the sweet spot in the control room and everybody is happy-

Please expand on these silence cases...

This topic came up on another board I frequent.

Here's the reason the small booth doesn't work. It's got very little to do with Whisper Room. FYI ...

Bottom line: 4 x 6 x 8 is sort of OK.

Voice-over Recording Studio
"VOICE-OVER" RECORDING IS THAT PROCESS BY WHICH A narration is recorded to later be used alone, or mixed with background music and/or sound effects. It can also be applied to the simple recording of voice alone. The studio for doing this is called a "voice" studio, with its particular acoustical characteristics, even as a "music" studio has its own acostical requirements. At first glance it might seem that the acoustical requirements for a voice studio would be simpler than those fo a music studio. This is not necessarily true. Voice sounds are subject to colorations (such as those caused by modal resonances and comb-filter effects), which can also affect music, but which are less audible in music.

What size should the voice studio be?
Although economic factors can outweigh the acoustical, there is a penalty in having a too-small studio. The modal resonances of the room are the acoustics of the room (see chapter 18). If the room is too small, modal resonance frequencies will be too few, with too-great spacing between them. This becomes a permanent flaw of the room, with no satisfactory correction. The smaller the room, the higher the low-frequency limit; that is, the lowest frequency with resonance support. For example, a room ten feet long will have a bass limit of 56Hz, but a 20-foot room will have a bass limit of 28Hz. Above 300 Hz the modal frequencies are so close together that problems associated with the lower frequencies tend to disappear.

The acoustical engineers of teh British Broadcasting Corporation (BBC), with their hunders of studios, have (on the basis of voice coloration studies) decided that it is impractical to build voice studios smaller than 1,500 Ft(cubed).

What shape should the voice studio be?
In this rectilinear world a rectangular shape is assumed, but what dimensional proportions should be selected? Scores of papers have been written presenting arguments about why certain room proportions give the most uniform distribution of room modes. All have strong and weak points; none result in the perfect distribution of modal frequencies. Here are three proportions that have stood the test of time:

A. 1.00 H 1.14 W 1.39 L
B. 1.00 H 1.28 W 1.54 L
C. 1.00 H 1.60 W 2.33 L

Assuming a ceiling height of ten feet, these three proportions offer the following:

A. 10.0 H 11.4 W 13.9 L 1,585 ft c
B. 10.0 H 12.8 W 15.4 L 1,971 ft c
C. 10.0 H 16.0 W 23.3 L 3,728 ft c

Proportion A gives a volume that has been classed as marginal in size for a room to be used for a voice studio. Proportion B is a bit better, but proportion C is selected as the most promising.

here is the review:

If no budget for a silence case exists, cutting a whole in an adjacent wall and putting the computer box in another room helps a bunch. I still have monitor, wireless keyboard/mouse and USB CD/DVD player/burner in the studio with me.

BTW: The only "room" at my place that is close to the dimensions listed is my garage... I may try it for vocals..? It's already insulated to a degree and has a well-insulated door. The "ceiling" is just 3" fiberglass at the 8' level, but "peaks"(Above the "bass-transparent" insulation) to about 12'. Total CF, should be between the BBC B and C standard, volume-wise, with the dimensions only slightly "off"... May be worth a shot(Or shout! Assuming the lawnmower has no peculiar resonances?).
