160,000 watts of RUSH — how loud is that, really? Turns out, only about 8 times louder than a 300 watt amp! And only about 16 times louder than a 30 watt amp!

The carryon about one-hundred and sixty thousands watts, holy cow, that’s huge! actually breaks down this way: Every doubling of power is represented as 3dB. It takes 10dB difference to make something sound “twice as loud” or “twice as quiet”. So 160,000 watts only sounds about twice as loud as 20,000 watts (that’s about 9dB … Read more

FREQUENCIES (2013) movie premieres memes of sing-song sounds, lyrical control words, and ancient aural technologies

Far more deeply interesting than the shallow, mindless write-ups and reviews would indicate. This movie touches on themes of mind, body, and soul as relating to resonance, vibration, speech and lyrical control. Dissonance between two erstwhile kindred spirits is finally overcome with old technology (made new again) that applies trigger words, sounds, and two-syllable phonemes … Read more

On the Fallacy of “Limited Bandwidth” in Guitar Amplification

Content Malcolm Moore explains why limitations are not preferable “For a guitar, the audio spectrum needs are wide. …The lower open E string has a fundamental of about 128 Hz, and significant harmonics are the second, fourth, sixth and eighth meaning the spectrum here extends to 1024 Hz. On the twelfth fret on the upper … Read more

Musical rhythm spectra from Bach to Joplin obey a 1/f power law

Much of our enjoyment of music comes from its balance of predictability and surprise. Musical pitch fluctuations follow a 1/f power law that precisely achieves this balance. Musical rhythms, especially those of Western classical music, are considered highly regular and predictable, and this predictability has been hypothesized to underlie rhythm’s contribution to our enjoyment of … Read more

Biological Effects of High Frequency Sound

“…results suggest the existence of a previously unrecognized response to complex sound containing particular types of high frequencies above the audible range. We term this phenomenon the ‘hypersonic effect.” May explain why most listeners can hear a supposedly impossibly high-frequency difference between a 12 kilo Hertz square wave versus a 12 kilo Hertz sine wave. … Read more
