It is based on orders of magnitude, rather than a standard linear scale, so each mark on the decibel scale is the previous mark multiplied by a value..

What is a normal volume for TV?
For most TV programmes audio hovers around PPM 5 1/2 and PPM6. Some dramas use a wider signal range, dropping below PPM3 and peaking at PPM6. With loudness meters we can make use of the wide loudness range but we make sure all the programmes average at -23LUFS.
What is perfect volume?
The “perfect volume” is something that changes with each nuance of the music and the changes happening throughout the service. To put all the responsibility for “how loud it is” on a dB meter is too simplistic and the wrong way to go about determining the audio levels in your services.

How is TV volume measured?
Internally the sound is measured in dB because that’s how the human ear perceives a change in sound pressure. … The total range of the TV might be divided by 100, so you have an arbitrary unit of sound pressure from 0 to 100, which might correspond to different increase in dB in different TVs.
What volume is too loud?
Decibel Level Sounds at or below 70 dBA are generally considered safe. Any sound at or above 85 dBA is more likely to damage your hearing over time. Researchers have found that people who are exposed over long periods of time to noise levels at 85 dBA or higher are at a much greater risk for hearing loss.
Why can’t I control the volume on my Samsung TV?

What is PCM audio on TV?
The PCM audio feature in a television allows the television to change an analog signal into a digital signal. The PCM process involves sampling the signal at regular intervals, as it periodically takes a measurement of its bit depth before converting it into a binary code.
Why are TV speakers so bad?
Manufacturers are constantly making their TVs thinner and the bezels smaller. This has forced the speakers into the back or the bottom, making them very tiny in the process. The problem is, speakers need to be bigger to produce decent sound. And it doesn’t help that they’re often facing down or away from you.
