    Does Turning up the Volume in Windows 10 Mean Consuming More Energy?

    I may be an energy saver, but I am being curious.

    Hmm... headphones or 500W speakers?

    Unless, as @dalchina hints, you're using some very powerful speakers... then no, turning up the volume won't consume any noticeable amount of energy.

    If you're really worried about energy usage, you can always get an inline watt meter...

    Plug it into the wall and plug whatever you want to measure, into the watt meter.

    Yes it does, however overall it would be a very small percent of the overall power consumption.
    Assuming you mean an integrated audio chipset then it would be some tens of milliwatts for let's say headphones, and maybe a hundred milliwatts for small speakers on a Laptop.
    That compared to the CPU+GPU and other electronics that maybe a few watts which depends a lot on what content is being used.

    Hi there

    "Bak2Skule" !!!!!

    Sound 101 -> the speaker vibrates according to the frequencies supplied to it by the amplifier (analog -- digital amps including phones have a DAC in them - "Digital Analog Converter" as the human ear can only hear analog). This vibration moves a volume of air in similar frequencies and this reaches the human ear as sound. The louder the volume the bigger the the volume of air that needs to be transmitted to the human ear. This requires energy -- so the question is really quite obvious -- more volume, more energy consumed.

    For small headphones and computer speakers left on relatively low volumes difference of energy is very small -- but if you like thumping out stuff like annoying teenageers in cars bashing out "Music ???" at incredible volumes then a lot of energy is consumed.
