Small Room Acoustics De-Mythologized - Eporia

®Figure 4 - Standing waves between two parallel surfacesNow we can begin to define the difference between large and small rooms. In a large room(smallest dimension of 50 feet or so), the standing waves will be multiples of very lowfrequencies. Two walls 50 feet apart will have a lowest resonant frequency of about 11Hz, and standing waves can exist at all multiples of this frequency. they are thus very closetogether by the time they get up into the audible range, and even though they are extremelynumerous, they tend to simply blend together fairly smoothly. This is the reasonlarge rooms always sound smoother and more uniform than small rooms. Of course, large7
