So from what is understood about the hearing of cats for example, is that they have one of the largest frequency ranges in mammals 48Hz – 79000Hz. Being most sensitive in the range of 500Hz – 35000Hz. Human range being 20Hz – 20000Hz. And a cat can hear sound at a level far less than the quietest we can hear.
I understand some sound system speakers go over this 20000Hz up to around 35000Hz.
It is clear that even the noise of aluminium foil can distress a cat and is believed to have caused seizures in some cases.
From a personal observation my cat would often sit by the front door of my first floor flat in busy South London, some minutes before my girlfriend arrived. She lived 5 minutes walk away. There were no routine visits involved.
