However, when a modulation transfer function MTF test is applied to the woofer of the aud... more |

In 2011, Acoustic Sciences Corporation won HomeTheaterReview.com's Best Of 2011 Award for their award winning line, the TubeTrap. HomeTheaterReview.com also reviewed our... more |
August 8, 2012 Goodwins Hi-End Customer who purchased: (2) 16x4s, (11) Tri-Panels, (1) 18” subtrap While it took me some time to appreciate it all, I can now confidently say that the ASC upgrade with the tube traps and the tri- panels is phenomenal. With good recordings the harshness that I was complaining about is gone, even without a DAC upgrade. I cannot believe how clean the sound is, while fortunately retaining the natural hardness (not harshness) of liv... more |

From an Invited Lecture "Sala Acustica" Given to Top Audio, The Hi End Audio Show In Milano Italy, October, 1991 by Arthur M. Noxon, PE, MSME, MS The Wall in the DesertAn old saying is known in many countries "The chain is only as strong as its weakest link."

TRAPPING BASS IN YOUR PROJECT STUDIO --By Arthur M. Noxon-- Sound is acoustic energy and rooms store this energy. Resonance is nature's most efficient way to store acoustic energy in a room. Resonant energy easily lasts two times longer than sounds that are not resonant, and this is how the coloration of sound occurs in small rooms. Originally written and published in dB Magazine, November/December 1991, and January/February 1992. Reprinted with permission of db Magazine, Co... more |

An auditorium is made for "auditing", or listening. A church is made for auditing and singing, therein lies the important difference.

Acoustic Carpets for High End Audio ApplicationsAll “acoustics” is not the same. We have sound proofing and then we have sound conditioning. Sound proofing means keeping the sound in the room and sound conditioning usually means getting the sound that’s in the room to calm down. Some carpet acoustic products are about soundproofing, reducing the sound transmitted to your neighbors, downstairs. Other carpet acoustics are about sound conditioning. In high end audio applications, there certainly wi... more |
