... The middle ear has two functions: 1. Impedance matching. Fluid in the cochlea is much harder to vibrate than air. If sound waves in the air struck the oval window directly, they would mostly bounce off. The ear drum picks up weak vibrations over a large area. The ossicles then act like a lever syste ...

... loudness of a sound is defined by its amplitude. The amplitude of a sound decides its intensity, which in turn is perceived by the ear as loudness. Page No: 167 1. In which of the three media, air, water or iron, does sound travel the fastest at a particular temperature? Answer The speed of sound de ...
