Apr 5, 2022 · Related: Amplitude is what we think of as the volume of a given sound, and this is expressed in decibels (dB). The frequency and amplitude of a sound are completely separate, though they both affect when a sound seems uncomfortably loud. One critical thing to keep in mind with decibels is that they increase exponentially, not linearly. One of the most important concepts in audio is the decibel, the unit of measure denoting the ratio of a change in level, whether that level is acoustic Sound Pressure Level (SPL) or electrical signal level. It’s abbreviated dB. As you may or may not be aware, the decibel (dB) scale is a logarithmic system, as opposed to a linear scale.
