" I am very satisfied with the WhisperRoom I purchased. When I play my trumpet in my booth it can not be heard two rooms over in my apartment. When it can be heard it is softer than a TV at normal volume. I think the single wall enclosure is just fine for use in the house. Although I plan to upgrade to the double wall in the future, I have had no complaints from any of my neighbors. The quality is very nice, and I think it was money well spent. It is especially great for recordings as well. I have a digital mixer in my booth and there is no background noise from outside the booth...even when the phone rings. I highly recommend purchasing one of these booths."
