Sound Power Level (SPL) Calculator. Sound Power Level (SPL) is defined as the rate at which sound energy is transferred or received per unit of time. The SI unit of the SPL is Watts(W). The SPL is also known as the acoustic power level. It is nothing but the power of the sound force on a surface of the medium of propagation of the sound wave.

Enter the sound pressure and reference pressure into the calculator to determine the sound pressure level, also known as dB level.

Acoustics - Room acoustics and acoustic properties - decibel A, B and C - Noise Rating (NR) curves, sound transmission, sound pressure, sound intensity and sound attenuation; Noise and Attenuation - Noise is usually defined as unwanted sound - noise, noise generation, silencers and attenuation in HVAC systems; Related Documents . SIL - Speech Interference Levels - Approximate Sound Pressure Level Calculation. Sound pressure level or sound level is a logarithmic measure of the rms sound pressure of a sound relative to a reference value. Here we can calculate Sound Pressure Level, Sound and Reference Pressure. Just copy and paste the below code to your webpage where you want to display this calculator. Sound pressure level calculations are the same as sound power level calculations detailed above, except the 20 log(p/po) factor applies, instead of the 10 log(w/wo) ratios.

Use the calculator below to calculate the sound pressure level at distance. L p1 - sound pressure level at location 1 (dB) R 1 - distance from source to location 1 (m, ft) L p1 - distance from source to location 2 (m, ft) Example - Noise from a Machine. The noise from a machine in distance 1 m is measured to 110 dB.

Sound Pressure Example. How to calculate a sound pressure? First, determine the sound pressure. Measure the total pressure of the sound. Next, determine the reference pressure. Most often this is just the atmospheric pressure. Finally, calculate the sound pressure level. Calculate the decibels of the sound using the equation above.

A sound pressure level is what we can physically measure using a sound level meter. Most noise level parameters in a report are based upon an SPL, albeit they are mostly adjusted in some way, i.e. weighted to a single number (dB(A)), or a level difference such as a Dw. A sound power level (SWL) is theoretical.

The threshold of hearing corresponds to the sound pressure level Lp = 0 dB at f = 1 kHz. Sound intensity I as Sound energy quantity: The auditory threshold is calculated as the reference sound intensity I0 = 10 −12 W/m 2. Since sound measuring instruments respond to sound pressure the "decibel" is generally associated with sound pressure level (SPL). Sound pressure levels quantify in decibels the strength of given sound sources. Sound pressure levels vary substantially with distance from the source, and also diminish as a result of intervening obstacles and The formula for the sum level of sound pressures of n incoherent radiating sources is The reference sound pressure p0 is 20 µPa = 0.00002 Pa = 2 × 10 −5 Pa (RMS) ≡ 0 dB. From the formula of the sound pressure level we find This inserted in the formula for the sound pressure level to calculate the sum level shows Levels of sound pressure and levels of sound intensity decrease equally with the distance from the sound source with 6 dB per distance doubling. There the soundpressure drops to a half and the sound intensity to a quarter of the initial value.

Sound pressure level L p is measured in decibels (dB) and is calculated as follows: L p = 20 log 10 (p/p 0), Where p is the root mean square sound pressure and p₀ is the reference sound pressure (usually 20 μPa or 0.00002 Pa). The sound pressure level is an absolute value because it is referenced to another absolute value — the threshold Use the calculator below to calculate the sound pressure level at distance. L p1 - sound pressure level at location 1 (dB) R 1 - distance from source to location 1 (m, ft) L p1 - distance from source to location 2 (m, ft) Example - Noise from a Machine. The noise from a machine in distance 1 m is measured to 110 dB.
