Hi,
the Audio engineering society lecture on the 11th of October is about Chameleon subwoofer arrays.
from the web site "Current work in the Audio Research Laboratory (ARL) at the University of Essex has engaged in the development of a flexible networked low-frequency response control system, termed a chameleon subwoofer array (CSA) due to its intrinsic capability of adapting to acoustical surroundings. CSA technology provides multiple degrees of freedom towards system correction, achieved either with multi-component subwoofers or standard single drive unit subwoofers calibrated automatically.2
meeting location, Please note: London lectures are now held at The Royal College of Pathologists, 2 Carlton House Terrace, London, SW1Y 5AF, just off Pall Mall (next door to the RAE). Meetings start at 7.00pm with refreshments from 6.30pm.

you don't need to be a member to come along to a meeting. there is no charge for entrance.

Sounds like a cardioid bass array, i.e. directional bass

Lots of live event sound systems are now using this technology to try and overcome noise pollution

Sounds interesting!

Hi

Yes, definitely sounds interesting - sadly, it's too costly to get to London for one meeting.  I'd be interested to know what this is about if you're going.

Hi!

This lecture was rather interesting but not for the reason assumed . . . It was more about achieving _even_ bass experience throughout a room rather than in any way forming a directional array.

The technique of controlling bass perception in a room achieved used a cube with two dipole radiators in the y and z axis and a monopole in the x axis situated in the corner of a room to control the three dimensional room eigenmodes.

But what was particularly interesting was the reported use of bass boost on walkmans and iPods and iPlayers but the way of generating a 2nd and 3rd harmonic of bass notes and using them to recreate the fundamental psychologically: technology has actually followed organ building with its tradition of Acoustic Bass 32ft . . .

Best wishes
