Jun 12, 2025 · At Seltech, we believe in making acoustics more accessible—so in this article, we go through a simple yet powerful formula to recalculate SPL for different distances and power …

Quickly find out how loud your speakers will be based on amplifier power, speaker sensitivity, and distance from the speaker with this calculator:

Oct 27, 2023 · Once we know the sensitivity, we can calculate SPL for a given input power, up to the max power handling. With power, the formula is 10 log (ratio), so 2x power = 3 dB and 10x …

Consequently, at 6 watts of power we obtain 103 dB SPL at a distance of 1 metre. There is also a mathematical formula for this calculation that yields the same result. Each doubling of power …

Two equal sources produce a 3 dB increase in sound power level. Two equal sources produce a 3 dB increase in sound pressure level, assuming no interference. Two 80 dB sources add to …

Sound power is the distance independent cause of this, whereas sound pressure is the distance-dependent effect. At r = 1 meter distance, the sound pressure level (SPL) of a point source is …

Jun 2, 2025 · Use this SPL calculator to convert sound pressure level to decibels, adjust for distance and power, and combine multiple sound sources easily.

May 31, 2022 · Just like you wouldn’t judge a Formula One car’s performance on its MPG rating, you would never judge a speaker on watts alone. Let’s look beyond power ratings to …

Mar 23, 2025 · You can see that sound intensity (acoustic power per area) is proportional to the square of the pressure amplitude, and it uses the 20 log10 form of the formula to give the …

Dec 31, 2024 · SPL Attenuation – A speaker’s data sheet usually specifies the SPL at 1 meter distance when the amplifier provides 1 Watt of power. This tool provides the formula and also …
