Typically, it is assumed to be equal to 10⁻¹² W/m² Iref - reference value if sound intensity. I - sound intensity in watts per squared meter The basic units are watts/m² or watts/cm². decibels 10 × 2 20 dB If we put all these steps together into a single equation, we once again have the definition of a decibel. ![]() log (100) log (102) 2 Multiply this result by 10 to find the number of decibels. The usual context is the measurement of sound intensity in the air at a listener's location. How do you calculate dB Find the logarithm of the power ratio. This calculator converts between decibels, voltage. Add or subtract decibel values Add or subtract dB (or dBA) values: result: Available operators: + - Use case: Subtract background noise Measure the sound level in dB or dBA with the sound source running and background noise present. Decibels convert multiplication and division calculations into simple addition and subtraction operations. Sound intensity is defined as the sound power per unit area. Decibel calculator for sound This page has a number of different calculators for sound and decibels. Typically, it is assumed to be equal to 0.00002 Pa Pref - reference value of sound pressure. P - sound wave pressure, measured in pascals SPL is measured in decibels (dB), because of the incredibly broad range of intensities we can hear. SPL is actually a ratio of the absolute, Sound Pressure and a reference level (usually the Threshold of Hearing, or the lowest intensity sound that can be heard by most people). Also, temperature and surrounding conditions, natural and man-made, all have an effect on the total sound output.DB Calculator are physic/math calculator to find sound pressure level (SPL) and sound intensity level (SIL) in decibels fast and easy. In certain cases, a really wide deviance can actually cause attenuation rather than amplification. The greater the deviance between the two levels, the smaller the amplification addition. ![]() As an example of anticipated data, if you were combining a 50 decibel level to another 50 decibel level, the result would be about 53 decibels rather than a total of the two. In the A-weighted system, the decibel values of sounds at low frequencies are reduced, compared with unweighted decibels, in which no correction is made. dBV refers to a voltage magnitude referenced to 1 volt, while dBu is referenced to 0.775 volts. ![]() Because decibels are logarithmic units and can't be added like other numbers, total combined output is not easily determined. A-weighted decibels (dBA, or dBa, or dB(a)): A-weighted decibels, abbreviated dBA, or dBa, or dB(a), are an expression of the relative loudness of sounds in air as perceived by the human ear. This audio tools provides a quick and convenient means to convert between them. Keep in mind that the calculation is approximate since there is no exact way to calculate decibels. This calculator is designed to give the total amount of decibels you can expect with a secondary sound source added to a primary sound source. Easily convert Sones to Decibels using this calculator.
