Home theater (HT) system owners understand the importance of sound control in the scope of overall home theater experience. Both sound isolation and sound absorption are features of HT that are necessary for creating the best possible home theater sound (and experience) possible. To address specific steps in sound control, home theater owners need to consider the role of bass traps for the emission of low frequency sounds in smaller spaces.
Bass trapping in a simplified sense is basically the capturing of low frequency sounds that are bouncing around your room typically generated by your subwoofer. The reason for these frequency sound bounce is as simple as the solution. The problem is in small rooms, or rooms under 7000 cubic feet in size.
Unlike very large rooms, for example a small opera house, concert listening halls, or normal commercial movie theaters, low frequency sound can resonate in almost any frequency smoothly from one note to the next. With small rooms, the transition of sound across frequencies is more difficult if not impossible.
Small rooms only have a few notes or a few tones that they will resonate at in the low frequency range. And it tends to make the reverberation part of the sound, the part that echoes after the initial impulse, to be less than smooth. In other words, some tones you will hear twice: first during the transmission of the sound and again during the echo and reverberation.
Low frequency sounds transmitted in smaller rooms differ from other tones and larger rooms. While some other tones are heard after their initial transmission, they are stopped dead in their tracks with no echo or reverberation.
The result is unnatural and not as pleasing. Additionally, it is one of the big differences that many home theater owners have trouble describing. It is, however, something most theater lovers notice between the sound experienced in the movie theater and the sound experienced in a HT.
The explanation for the differences among room sizes is found in the acoustic elements. It is not that listeners dislike or cannot enjoy reverberations low in the band. It is that small rooms cannot physically reverberate smoothly across a low frequency band. When home theater spaces are not large enough to accommodate the sound demands of sound transmissions, they are unable to smoothly reverberate low in the band.
To explain the difference in context, a 100 Hz wave is an 11 foot long low frequency wave. Due to the size of both the wave and the room, there is no way such a wave can smoothly reverberate in the space on the order of say 14 by 20 by 9. The larger low frequency waves they just cannot bounce around the available space and reverberate smoothly.
The first job in acoustic treatment in home theaters to absorb those low frequency signals so that all the different tones sound uniform in character. The overall desired result is the ability to listen to them accurately and smoothly.
Sound control is an area of concern for HT owners with smaller theater spaces. Room treatment that addresses the demands of low frequency transmission and the limitations of smaller rooms can enhance and improve your HT experience for an infinite amount of theater enjoyment.
