Does volume really affect power?


Unregistered guest
Hi, does raising tv or radio volume cause a significant encrease in power consumption? I mean, i totally understand how that can wear down batteries, but would constantly playing my televion on full volume significantly affect the electricity bill?

of course it does.

every time you raise your volume just 3 decibles, you need to double your amplifier's power. the higher the volume level, the greater the power consumption. at 100 watts... 3 more decibles requires 100 watts.

the cost increase to your power bill at higher volumes shouldn't really be that significant though unless you're listening to 5 channels at ear splitting levels all day every day.

most of your music listening is probably only 1-10 watts with full power only at brief peaks.
