What is a Gilbert cell amplifier?
Yup. It’s called a Gilbert Cell or a Transconductance amplifier and it uses varying amounts of current to set the gain. The beauty of this scheme is regardless of the gain the performance of the amplifier is unchanged. Thus for any given level the sound will be the same. It’s used a lot in analog recording consoles.
Is turning up the volume like pressing the gas pedal?
Paul. I do feel that turning up the volume is a bit like pressing the gas pedal. You are increasing the signal level into your power amp. If it is the normal fixed gain class AB design, without signal it will be idling; drawing little current and (hopefully) making no sound. As the level of the input signal increases it draws more current and the output volume rises (as does the total distortion, although crossover distortion is largely volume independent and is thus more noticeable at low volume)

Can you control volume on a speaker?
Today, we can play an audio signal on everything, but the speakers built into most devices leave something to be desired. Hooking up to external speakers and amps help fix that problem, but controlling the volume on these setups can get clunky. Enter the volume control circuit. A quick setup will allow you to add a dial to any speaker system so you can control the volume without having to interact with the device you’re playing it on.
What is a volume limiter?
A volume limiter literally limits audio output to a specified, safe listening level. Also known as integrated “hearing safeguarding,” they’re a popular feature in kids headphones, but they’re also available in products for adults. Level limiters usually aim to limit the maximum volume to 85dB (SPL) or less.
How does volume limiting work?
A hardware volume limiter can either be a part of the headphone or an in-line adapter—usually a cable—that sits between the audio source and the headphone. A software volume limiter is built in as a feature in your smartphone or media player.
How do headphones work?
Essentially, headphones transform electrical energy into sound waves, which is exactly how loudspeakers work. Technically speaking, that makes them transducers.

Headphones can produce sounds of more than 115dB (SPL). That’s equivalent to a rock concert and way too loud for extended listening periods. 80dB (SPL) is a safe volume for all-day listening, but even at that level, your ears need regular breaks.
What is an active earbud?
Active headphones have a battery to power the electronics, typically to provide onboard EQ or active noise cancelling ( ANC ); though these are rarely analog nowadays, as digital technology is superior and more cost-effective. Devices like this have active amplification stages that drive the transducers. Analog limiting circuits (automatic gain controls) can impose a maximum output voltage to the transducers, calibrated to correspond to a maximum SPL (output volume level).
How to set volume limit on Android phone?
Not all Android devices let you set a volume limit, but Samsung phones and several others do.
