"WebThe decibel scale is a logarithmic scale in which the doubling of the sound pressure level corresponds to a level increase of 6 dB. Decibels are not fixed values like volts or meters. There are various dB scales depending upon the environment through which the sound travels. In audiometry we use a calibrated decibel hearing level scale (dBHL). " - Hearing logaritmic

WebThe Weber–Fechner laws are two related hypotheses in the field of psychophysics, known as Weber's law and Fechner's law. Both laws relate to human perception, more specifically the relation between the actual change in a physical stimulus and the perceived change. This includes stimuli to all senses: vision, hearing, taste, touch, and smell. WebThe relationship between the intensity of a sound wave and its pressure amplitude (or pressure variation Δ p) is. I = ( Δ p) 2 2 ρ v w, 14.6. where ρ is the density of the material in which the sound wave travels, in units of kg/m 3, and v is the speed of sound in the medium, in units of m/s.
