Understanding decibels in audio work - Geoff the Grey Geek

    Understanding Decibels (part 2) In the first article we saw that a decibel is not a fixed unit, rather, it is a ratio between two levels. A decibel... Understanding Audio.

Understanding Decibels [2022] Scale / Level / Loud / Normal

    In decibels, sound is expressed in (dB). A whisper is about 30 dB, regular talk is about 60 dB, and it is about 95 dB for a motorcycle engine to operate. Noise over 70 dB can start to affect your hearing for an extended period of time. …

Decibels 101: A Musicians Guide to Basic Understanding

    In music, decibels are a measurement of Sound Pressure Level (SPL). When we say the speakers at a rock concert are playing at 110dB, what we really mean is that they’re playing at 110dB SPL. Since the decibel is only a ratio, 110dB is actually a comparison to a different number: 0 SPL.

The Decibel (dB) Scale & Audio Rules 101 | Audioholics

    One of the most important concepts in audio is the decibel, the unit of measure denoting the ratio of a change in level, whether that level is acoustic Sound Pressure Level (SPL) or electrical signal level. It’s abbreviated dB. As you may or may not be aware, the decibel (dB) scale is a logarithmic system, as opposed to a linear scale.

The Decibel Scale, A Practical Understanding

    The decibel scale can be used to measure audio in a variety of different ways. The decibel can be used to measure sound pressure level, sound intensity level, voltage level and power, just to name a few. This provides a valuable reference tool for the audio engineer, technical engineer, and the audio equipment designer.

dB: What is a decibel? - University of New South Wales

    sound level = 20 log (pmeasured/pref) = 20 log 1 = 0 dB. Remember that decibels measure a ratio. 0 dB occurs when you take the log of a ratio of 1 (log 1 = 0). So 0 dB does not mean no sound, it means a sound level where the sound pressure is equal to that of the reference level.
