In contrast, decibels are measured on a logarithmic scale. HVI is the Home Ventilation Institute, an industry organization that provides accurate and independent third-party testing for bathroom fans and other types of household fans. Click the Convert button, and the missing value will be filled in. P - Sound pressure, Pa. Pref - reference sound pressure, 0.00002 Pa. As an example, the sound pressure from a . 1 Sone is equal to 28 dB. Note: Technically, decibels are a measurement . And the list goes on. This keeps the sound produced from your blower at bay. One decibel (0.1 bel) equals 10 times the common logarithm of the power ratio. Start with the mounting nut holding the blade to the motor assembly. The sound intensity level (SIL), also called acoustic intensity level, is the absolute logarithmic unit of the sound intensity relative to a reference value of 10 W/m human hearing threshold in the air.
