Here is a really interesting post about a presentation made by international speaker and sound/audio expert Julian Treasure, author of the “Sound Business” blog. The video of that presentation can be seen below.
Treasure offers 10 things “you didn’t know about sound,” some of which are absolutely true, and some of which are a bit theoretical and heady – such as “your body is a chord.” Treasure makes some claims in this presentation about sound and its relationship to health that are followed by the statement – “…I hope [this] will be tested by researchers.“So just be aware of that.
One of the things he talks about is the auditory frequency range of humans – 20 Hz to 20,000 Hz – which is definitely true and impacts a lot of the standards for audio recording, especially things like digital audio and A-D (analog-to-digital) converters, and most specifically, sampling frequency. See our article What Is Sampling Frequency?
