In Reply to: MUSIC NOTES BELOW 27 HZ?? posted by ARAM on July 28, 2002 at 03:18:07:
While the lowest note on a full sized piano is 27hz, it is seldom played. Tympani are tuned to 25hz, but when played loudly double. The lowest note on a 4 string bass is 42hz, but its 2nd harmonic is usually 8~10dB louder(5 string is 31hz). A few years ago the Journal of the Audio Engineering Society (JAES) did a music survey with a spectrum analyzer. 98% didn't go below 40hz, 99.99% didn't go below 28hz, and you could count on one hand ones that went below 28hz (and they were all synthesized). If you hold the box size constant, going from 40hz to 28hz costs you 4.65dB, and going from 28hz to 20hz another 4.35dB .
)I used to build and sell what I thought was the optimum trade-off, a 40hz sized box with 28hz 'step-down-tuning'. On 98% of the music it had 9dB more output than the 20hz box. A modest amount of EQ was designed in to the amplifier to make it flat to 28hz. While there is no such thing as a free lunch, good engineering choices can seem almost 'free'.
