WebWhen the defining level of 0 decibel (10 -12 watt per square metre) is taken to be at the threshold of hearing for a sound wave with a frequency of 1,000 hertz, then 130 decibels (10 watts per square metre) corresponds to the threshold of feeling, or the threshold of pain. WebThe decibel measures sound pressure or electrical pressure (voltage) levels. It is a logarithmic unit that describes a ratio of two intensities, such as two different sound pressures, two different voltages, and so on. A bel (named after Alexander Graham Bell) is a base-ten logarithm of the ratio between two signals. glenrothes clubsWebThe physical phenomenon of sound is a disturbance of matter that is transmitted from its source outward.Hearing is the perception of sound, just as seeing is the perception of visible light.

WebPeople get wavelength and period mixed up all the time. The period of a sound wave is the time it takes for an air molecule to oscillate back and forth one time. The wavelength of a sound wave is the distance between two compressed regions of air. People get these mixed up because there's an alternate way to create a graph of this sound wave. WebSounds that are not periodic (or quasi-periodic) are called aperiodic. Aperiodic sounds are sounds that do not repeat There are two ways we can imagine that a sound would not repeat A transient sound is one that occurs just once, briefly (For example, a popping balloon, dropping a pen, or synthesizing one cycle of a sine wave)
