Relationship between speaker wattage and volume
When it comes to the "loudness" of speakers, many people seem to have a confused understanding of this concept When it comes to volume, many musicians only consider the power and rated wattage of the speaker. In general, the more wattage, the greater the loudness.
When it comes to the "loudness" of speakers, many people seem to have a confused understanding of this concept When it comes to volume, many musicians only consider the power and rated wattage of the speaker. In general, more wattage does not mean more loudness However, it is undeniable that watt is still an important factor to consider, and the power of speakers is also an important factor affecting the loudness of speakers
Decibel and volume level
Decibel (dB for short) is a unit of counting about the ratio between two numbers Well, I understand that many people are not interested in this, so I will simplify things and try not to involve "math" problems As for the logarithmic scale, you can't just understand it in a conventional way - for example, doubling the number will increase, but it doesn't mean "double". For example, 100dB is twice as much as 50dB, but it doesn't mean that its "loudness" is "twice as much as 50dB When it comes to "loudness", it refers to the sound pressure level (also known as SPL). The increase of about 10dB will "double" the loudness In other words, if a speaker that can produce 90dB SPL is compared with a speaker that can produce 100dB, most listeners will think that the second speaker has about twice the "loudness" of the first speaker.
Watts, Power and SPL
How many watts will double the loudness? Let's imagine that there are two types of speakers, one is 10W and the other is 20W The wattage of a 20W speaker is twice that of another speaker, but after conversion, the double wattage will only increase 3dB SPL Remember, if you want to double the loudness of the speaker, you need to increase the loudness of the speaker by 10dB. Although a 20W speaker is twice as loud as a 10W speaker in terms of wattage, it will not produce twice the loudness. The same is true in high-power equipment. A 100W speaker will not produce twice the loudness of a 50W speaker Assuming the same speaker, it will only increase the loudness by 3dB. Although the volume change will be very obvious, it will never double the loudness
Speaker sensitivity level
Speakers in speakers also have specifications for sensitivity and effect - they convert the input electrical energy into sound energy Dynamic dynamic loudspeaker (you can find it in most guitars and bass speakers) is very inefficient. It will convert most of the input power into heat instead of sound Generally, the sensitivity of loudspeakers will be measured in an anechoic room (a room without reflection and sound insulation) and described by such units/formats as: 90dB@1W /1m.
