Alla ljud som vi hör är egentligen bara lufttryckssvängningar som träffar vår trumhinna. Först när de förs vidare till vår hjärna så omvandlas de till information. Beroende på med vilken energi svängningen (ljudet) träffar trumhinnan så hör vi antingen tyst eller högt Ljudnivå är benämningen för hur högt ett ljud upplevs, t.ex hur högt ljud du skruvar upp på din stereo. Ett annat ord för ljudnivå är ljudvolym och dessa nivåer mäts i mätvärdet decibel (db). Ljudnivån är helt avgörande för hur behagligt ett ljud ska upplevas. Om ljudet har en låg nivå så blir det behagligt [ The decibel A filter is widely used. dB(A) roughly corresponds to the inverse of the 40 dB (at 1 kHz) equal-loudness curve for the human ear. With the dB(A) filter the sound level meter is less sensitive to very high and very low frequencies. Measurements made with this scale are expressed as dB(A)

There are plenty of free options available, but some apps may have ads or in-app. Decibel Addition and Subtraction Sound levels are generally expressed in decibels, which are logarithmic and so cannot be manipulated without being converted back to a linear scale. You must first antilog each number, add or subtract and then log them again in the following way

Useful for converting decibals into amplitude scale factors. For example, calculate the amplitude scaling factor if you want to adjust a sound waveform by -3dB or +6dB, or find out what the decibel difference would be if you scaled the waveform by 0.75. This can be useful, for example, when encoding audio (e.g. using LAME for MP3) to a target ReplayGain value The decibel (dB) is one tenth of a The quietest thing any human can hear, I 0, is one trillionth of a watt per square meter. So, if a sound is twice as intense as I 0, its intensity will be \[ 10\log_{10} \left [\frac{2I_0}{I_0 Online Tone Generator utilises HTML5 and the Web Audio API
