Understanding Wattage, Speaker Efficiency, and Amplifier ...

Understanding Wattage, Speaker Efficiency, and Amplifier ...

So, what are decibels exactly? Decibels (abbreviated "dB") are a logarithmic unit of measurement that pertain to a ratio between two numbers. Okay, we can see eyes rolling and glazing over, so we'll simplify things, and attempt to keep the "math" to an absolute minimum. With a logarithmic scale, you can't just add numbers in the usual way—a doubled number isn't "twice as much," but rather, many times more. For example, 100dB is many times greater than 50dB, not just "twice as much." When ites to "loudness," which is measured in Sound Preease in level is roughly equivalent to a "doubling" of perceived loudness. In other words, if one amp is generating 90dB SPL and another amp is hitting 100dB SPL, the second amp will generally be perceived to sound about twice as "loud" to the typical listener. See full list on So how many watts does it take to get twice as loud? Let's imagine two amps—one amp rated at 10 watts, and a second amplifier rated at 20 watts. The 20-watt amp is double the power of the 10-watt amp, but doubling thease of 3 dB SPL. Remember, in order to soundease of 10dB, so while a 20W amplifier will sound noticeably louder than a 10W amp, it will not sound twice as loud. The same thing holds true at higher wattages—a 100W amp is not going to sound twice as loud as a 50W amp assuming identical speakers, it will only be 3 dB louder, which is noticeable, but definitely not a doubling of perceived loudness. See full list on Speakershave specifications in terms of their sensitivity and efficiency—ming electrical energy into acoustical energy. Dynamic, moving coil speakers (the type found in most guitar and bass amps) are notoriouslyming power is actually converted into heat, not sound. Normally, speaker sensitivity is measured in an anechoic chamber (non-reflective, soundproof room) and expressed something like this: 90 dB @ 1W/1m. Translated into English, that means "90 decibels (SPL) with one watt of power, and measured at a distance of one meter from the speaker." A more efficient speaker will have a higher number and a less efficient speaker will have a lower number. See full list on So, let's assume we have a speaker with a sensitivity of 90 dB @ 1W/1m and a power handling capa of up to 100W. If that speaker is powered with 1W of power, it will generate 90dB when measured at a distance of 1 meter. If we double that power toease the power to 10W, ease to 100dB, which is "twice the perceived loudness" whenpared to 1W. So it actually takes 10 times more power to give us a perceiv this imaginary speaker is rated to safely handle up to 100W, we could double that volume level yet again, and in teasing the power all the way up to 100W. One watt=90 dB. One hundred watts, or 100X morease in power butease in terms of perceived volume levels! As you ceases in power—in the wattage of the amplifier—to "double... See full list on
