As mentioned in another post our furry friend recently injured herself on holiday. As we were out of her familiar surroundings/routine we found she was quite anxious which was very unusual for her - she is incredibly resilient. By accident we found that leaving music on at 432 hz in the background helped her a lot and reduced her level of anxiety over her injury which caused her pain when she walked. Clearly this won't be for everyone but FWIW we have been using this clip on YouTube.

very interesting, thank you

I can highly recommend this type of relaxation music for humans as well. I had a drug that gave me insomnia when I had cancer years ago and I used to drift off to a relaxation CD. I also have one of the sea which is lovely, like lying on a deserted beach. So very calming.

432 Hz is nonsense.

Al frequencies are defined by humans

I agree; whether A is tuned to 440Hz or 432Hz makes no difference whatsoever. Furthermore, the only note in the entire piece that's "tuned" to 432Hz is the natural A after middle C.

In the past some orchestras tuned to 435, 439, or 451Hz. I read that even today there are some philarmonics that tune to 442Hz.
