My Room Acoustics Part 2

Some background reading..............if you like............. http://medicine.jrank.org/pages/777/Hearing-Auditory-performance.html Three Acoustical Issues that Room Correction Can’t Correct http://www.hifizine.com/2010/09/the-three-acoustical-issues-a-room-correction-product-can%E2%80%99t-actually-correct/ In a nutshell............ Issue number 1: place a subwoofer at the corners of the room. To reduce the problem of speaker boundary interference response(SBIR for short). /I choose to have 1 subwoofer each in the front section of the room, 1 on the left corner and 1 more on the right corner. /That's will be 2 subwoofers specifically used to for this purpose and not doing the main task of reproducing enough bass contents to add to the sound of the main speakers. This helps explain 1 of several reasons for the introduction of additional subwoofers for the sole purpose of reproducing bass contents to emerge with those of produce by the main speakers, ie. integrate the bass contents. A total of 7 subwoofers are in placed at the time of writing. Issue number 2: reduce/control of early sound reflections from the many surfaces of the room relative to those direct sound from the speakers. /Work out a suitable combination of direct and reflected sound for that particular small room with acoustic treatments. The level of reflections can only be controlled through appropriate use of absorption or diffusion or by selecting speakers. /I choose the use of the ceiling treatments for a small room and at the 1st reflection point from the position of the speakers. And the choice of speakers happens to be very unorthodox. Issue number 3: rt60 cannot apply in a small listening room. The decay time of the room can only be brought to the level needed for high quality sound reproduction through appropriate decorative choices, furnishings and the use of acoustic treatment.............. /A simple hand clap will tell! Reduce the long reverberation time to bring up the sound quality, by reducing any overlapping of sound to perceive much readily the time gaps between individual sounds if any.
