This informative piece by writer Chris Berdik discusses the problem of restaurant noise and a new technological solution to it, the Constellation audio system. The Constellation system uses microphones, speakers, and computer processing to tune a restaurant’s sound environment to sound quieter. A lot of sound absorbing material must be installed to make the room acoustically “dead” before the Constellation system is installed.
As discussed in this article in Acoustics Today, getting the acoustics right in a restaurant can be a challenge. Diners want to be able to converse with those at their table, but want enough ambient noise to provide speech privacy for their conversations–and they don’t want to hear the conversations at neighboring tables. They want some sound, so the restaurant isn’t as quiet as a tomb, but not too much. And the acoustic characteristics of the restaurant change, both in terms of noise production and sound absorption, as the restaurant goes from half empty to chock-a-block full.
The developers of the Constellation system are trying to bring the price down. It’s currently $60-80,000, which is a lot of money. If restaurateurs want to make their restaurants more inviting for patrons, they will find the funds to make the space comfortable and inviting.
Of course, one of the first principles of acoustics is that the easiest way to make a space quieter is to reduce the noise at its source. And the cheapest and easiest way to reduce restaurant noise costs nothing: turn down the volume of the amplified background music, which often is turned up to rock concert levels!
