    The loudspeaker (OmniPower Sound Source) is fed with white noise in 1/3 octave band. The averaged sound pressure level was measured in 1/3 octave band frequencies, from 100 Hz to 5000 Hz. The microphone positions are located at 1 m in front of the test specimen. See full list on physicsclassroom.com Generally speaking, the more markings below 25 dB or more, at frequencies which are normally used in conversation, the more difficult it is to hear what is being said. And in situations with a lot of background noise, it will often be even more difficult to hear speech and other sounds properly.

    The phon amplitude scale is simply the dB scale at 1kHz [79, p. 111]. At other frequencies, the amplitude in phons is defined by following the equal-loudness curve over to 1 kHz and reading off the level there in dB SPL. In other words, all pure tones have the same loudness at the same phon level, and 1 kHz is used to set the reference in dB ...

    Mar 07, 2010 · A sone is a measurement of sound in terms of the comfortable hearing level for the average listener. The lower the sone value, the more comfortable the listening environment will be. For your question, a 4-sone rating is about four times a loud as a 0.9 (~1) sone rating. Sones are not decibels or volume, but rather how sound is sensed. Sones ...

Sound that is radiated from a point source drops in level at 6 dB per doubling of distance. Equation used to calculate the data: Snew = Sref + (20 * Log (Dref / Dnew))
