While the long decay of a classical hall makes an orchestra sound rich and full, a rock band playing in the same space may sound I.C.E. Tech - Noise & Music and distant because excellent-sounding rock and pop music depends on an amplification and loudspeaker system, which benefits from shorter reverberation times at low frequencies in the Hertz Hz octave bands. Danish jazz and rock drummer, Niels W. Adelman-Larsen, set out to help concert halls accommodate acoustic variability over a range of musical styles while still a student of acoustics at the Technical University of Denmark in Kongens Lyngby.
Over the past 10 years he developed a patented inflatable, adaptable absorption system that modifies the reverberation time of a room.
When the membranes are inflated, the plastic foil vibrates due to the different sound levels on the inside and outside of the cavity. The vibrations lower the reverberation time of the room. When the switch is on the off position and the membranes are deflated, this absorption effect is avoided, allowing for the long reverberation times most suited to classical music.
The whole system can be mounted flush to walls or above a sound transparent ceiling so it is not visibly intrusive. Certified measurements of the reverberation time show the activated absorbers can lower the reverberation time of a hall by up to nearly 45 percent in the relevant octave bands for rock and pop music.
Across the frequency bands fromhertz Hzthe absorption coefficients Introduction - Psychic TV - Southern Comfort nearly constant. Explore further. More from Other Physics Topics. Your feedback will go directly to Science X editors.
