The intensity of sound is measured on the decibel scale, db. The equation db=10logi represents the decibel level, where i is the ratio of the sound to the human hearing threshold. A noise registers a decibel level of 29. Which equation could be used to find how many times greater the noise is than the human hearing threshold?.

Respuesta :

The noise level is I=1029 I=log2 times over the threshold of human hearing.

How is dB measured?

Logarithmic scales are used to measure decibels. This is a method of accounting for or measuring an exponentially growing quantity. For instance, every 10 dB increase in decibels corresponds to a 10-fold increase in sound pressure level (SPL).

What is the formula for sound frequency?

The formula for sound speed is vw=f, where f is sound frequency and is sound wavelength. The distance between adjacent, identical wave components, such as between adjacent compressions, determines a sound's wavelength.

What is frequency measured in?

The hertz is the SI unit for frequency (Hz). One cycle per second equals one hertz.
