For small amplitudes, sound pressure and particle velocity are linearly related and their ratio is the acoustic impedance. The acoustic impedance depends on both the characteristics of the wave and the medium. The local instantaneous sound intensity is the product of the sound pressure and the acoustic particle velocity and is, therefore, a vector quantity.\u0026lt;\/td\u0026gt;\u0026lt;\/tr\u0026gt;\u0026lt;\/table\u0026gt;] cssheader=[boxoverheader] cssbody=[boxoverbody]\"\u003eSPL\u003c\/span\u003e\u003c\/span\u003e: 108 \u003cspan class=\"dictionary\" title=\"header=[\u0026lt;span class=boxoverheaderplain\u0026gt;Definition of\u0026lt;\/span\u0026gt; dB:] body=[\u0026lt;table\u0026gt;\u0026lt;td\u0026gt;The decibel (dB) is a logarithmic unit of measurement that expresses the magnitude of a physical quantity (usually power or intensity) relative to a specified or implied reference level.
