- wingerlang 10y agoI don't know really know what this means tbh, but here's an explanation: http://www.acousticfields.com/white-noise-definition-vs-pink-noise/ http://www.acousticfields.com/white-noise-definition-vs-pink...
- jrockway 10y agoIt's white noise with a different power distribution; low frequencies are louder: http://i.stack.imgur.com/MMr0a.png http://i.stack.imgur.com/MMr0a.png

- leblancfg 10y agoThe sound is distinctly crisper on BigQuery, though. Of course, cables can make a difference but not always -- use CAT-8.2 if possible.
- timpattinson 10y agoBecause humans hear frequency in log scale, pink noise has more "even" distribution of amplitude to our ears. Pink noise -> 100-200hz has the same power as 10k-20k ie each octave has equal power AFAIK.
- wrigby 10y agoWhite noise is defined as having equal energy per frequency; that is, a 10hz wide slice of spectrum centered on 100hz will have as much energy in it as a 10hz wide slice of spectrum centered on 1khz. Pink noise has equal energy per octave; the slice of spectrum from 40hz-80hz has as much energy as the slice from 80hz-160hz and the slice from 1khz to 2khz. Pink noise can be thought of as white noise with a very low-q (3dB per-octave, specifically) low-pass filter applied.
