sone to decibel calculator. Thats why we might be surprised when we see noise levels expressed in Sones. Absorb the sound. Decibels represent the amplitude of a sound. Six sones are about equivalent to the noise level of an electric fan. The noise level from the fan in decibel can be calculated as, The difference in decibel between sound intensity 10-8 W/m2 and sound intensity 10-4 W/m2 (10000 units) can be calculated as, L = 10 log ((10-4 W/m2) / (10-12 W/m2)) - 10 log ((10-8 W/m2) / (10-12 W/m2)), Increasing the sound intensity by a factor of. The Hauslane UC-PS18 features a 6-speed setting, allowing for maximum control over noise and performance. Follow this chart instead: Most range hoods have a range hood noise rating of roughly 6 to 10 sones. Installing a range hood improperly can affect its performance and noise level. Calculating decibels is typically a process of converting a sound intensity in one unit to another. Example: A bathroom exhaust fan has noise levels of 1 Sone. If human beings are exposed to loud noises for a brief period, it doesn't cause . All rights reserved. But sones is used quite commonly for household items like bathroom ventilation fans, aka bathroom fans and bathroom exhaust fans. For a 1 kHz tone above 40 dB, perceived loudness doubles every 10 dB.

(Using a 4-inch duct on a 6-inch fan will increase the loudness by 30%) You can find a Sones to Decibels calculator here. The decibel level of a signal can be expressed as, L = 10 log (S / Sref) (1), S = signal - intensity or power level (signal unit), Sref = reference signal - intensity or power level (signal unit). If I had to approximate (very loosely), I would guess that if 1 sone = 40 dB, and we add three decibels every time we double the amount of sound, we would get (very) roughly the following: 1 sone = 40 dB 2 sones = 43 dB 3 sones = 44.7 dB 4 sones = 46 dB Check the sones level of the range hood prior to purchase.

The sone rating system of loudness could be less relevant to someone with high frequency hearing loss because of the inability to hear well and separate different sounds. For a pure tone at 1 kHz, loudness in phon equals sound pressure level in decibels (dB). But sones is used quite commonly for household items like bathroom ventilation fans, aka bathroom fans and bathroom exhaust fans. To find how many decibels are in one sone, plug one into the equation: dB = 33.2*log 10 (1) + 28 = 28 dB If you have decibels and want to find the number of sones, use this equation: Sones = 10 ( (db-28)/33.2) These equations may look daunting which is why we made calculation easy for you. air), Latent Heat (BTU/hr) = 0.69 x CFM x gr. Range hood sound levels can vary. Expressed as a formula, the intensity of a sound in decibels is 10 log 10 ( S1 / S2 ), where S1 and S2 are the intensity of the two sounds; i.e., doubling the intensity of a sound means an increase of a little more than 3 dB.
