The Ear’s Capacity.

It has been found by Dr. Lawson Tait that, as a rule, the ear in women can perceive higher notes —that is, sounds with a greater number of vibrations per second—than the ear in men. The highest limit of and ability for the human ear is somewhere between 41,000 and 42,000 vibrations. The ears of most persons seem to be unequally sensitive to acute sounds, the right ear usually hearing a higher note than the left. To show the ear’s range, it may be added that very low notes of about fifteen vibrations per second may be perceived, but when the vibrations become a little slower they cease to produce the effect of a continuous sound, and each gives a separate inpression upon the ear.
