Well, you know the question. :smile:

Hi all Does anyone know the time delay through the head between the voicebox producing sound and the ear registering it? Thanks in advance Dave

Sound Problem... A swimmer with one ear underwater and one ear above water in air, hears a crash. She hears the crash in the water first where the Veloctiy of the wave in water was 1500m/s. The air temperature is 20°C and she hears the wave again after 2.0 seconds but this time she hears it...

I have just read an article about a species of fly (I wish I could remember the name of the fly, but I can't ("Omri something-or-other")) that have the hearing precision of an owl (it is said to be able to pin-point an object (through hearing) with a precision that is within two compass...
