Convert BTU To Tons: How Many BTU In A Ton? 2 sones are twice as loud as 1 sone and 4 sones are twice as loud as 2 sones. To achieve this consistency, the sounds are generated for the hearing jury at different combinations of decibels (sound pressure level) and Hertz (frequency). For a pure tone at 1 kHz, loudness in phon equals sound pressure level in decibels (dB). Sones represent perceived loudness of sound which includes sound wave frequency as measured in Hertz. Which is why you see the sound curves in the chart above. To calculate the decibels, multiply 10 by the logarithm of the ratio of the sound intensity to the reference sound intensity. https://hauslane.com/blogs/news/everything-you-need-to-know-about-sones-rating-for-range-hoods Sones To dB Chart.

One that is more powerful than necessary will make more noise too. The absolute means it can be easily converted into the sound level and vice versa. 0000002567 00000 n It is also widely used in electronics, signals and communication. The calculator below can used to calculate the NC - Noise Criterion: Sound Pressure Level (dB) - Octave band mid-frequency (Hz). This means that 0.3 Sone is equal to 10.64 dB. But below 40 dB, perceived loudness drops off more quickly; it takes less than a 10 dB reduction in sound pressure level below 40 dB in order for humans to perceive the loudness as having been cut in half.
