What is a sonometer measurement?

A sonometer is an instrument used for measuring the density, frequency and tension of vibrations. It is made out of a hollow box, which contains two holes. A string ,or monchord, is attached to the box so that the vibrations of the string can be measured.

Sonometers are used in medical institutions to test bone density and hearing. An audiometer or sonometer is used to measure the sensitivity of hearing, while a clinical bone sonometer measures the bone sensitivity. A bone sonometer is useful in measuring the risk of fractures associated with osteoporosis and is commonly used as a risk management tool.
