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 …
What is dB (decibel) and Frequency? - Learn about dB ...
https://www.hear-it.org/what-db-and-frequency
The frequency of a sound is the number of cycles of a sound wave in one second. The unit of measurement is hertz (Hz). The frequency of a sound increases as the number of cycles per second increase. Vibrations between 20 and 20,000 cycles per second are interpreted as sound by a normal healthy person. A high-pitched sound could be a piccolo flute or a bird singing.

Understanding dB for sound. Our ears expand when it is quiet to hear detail and contract when it is loud. 1dB = x 1.26 power change we hear as smallest loudness difference (laboratory only). 1dB sound change is too small and not …
Understanding Sound and the Decibel - BestCarAudio.com

The Decibel and Sound Level Measurement When discussing sound levels, the proper format is to use the unit dB SPL, dB (SPL) or dBSPL. The reference for any statement is the sound pressure as compared to 0dB. 0dB is defined as the perceived sound of a mosquito at a distance of 10 feet from the listener.
Understanding Frequency Response - Why it Matters
https://www.alesis.com/kb/article/2227
The dB scale is logarithmic (not linear), so 10dB louder is “twice as loud.” So for example, a speaker or headphone may be said to have a frequency response of 40Hz–20kHz (that’s the range), ± 3dB (that’s the variation). If a manufacturer specifies a frequency response without a ± xdB variation, it should set off a “Danger, Will Robinson!” alarm.

Frequencies range from low pitch to high pitch and read from left to right on the audiogram. Each vertical line represents a different frequency, such as 250, 500, 1000, 2000, 4000 and 8000 Hz. Intensity The intensity is measured in decibels (dB). The intensity relates to how loud or soft a …
Decibels 101: A Musicians Guide to Basic Understanding
https://ehomerecordingstudio.com/decibels/
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.

Frequency determines the tone of the sound Decibel determines the intensity of sound — Frequency: how sound waves travel The wavelength determines the sound frequency. It is measured as the number of repetitive vibrations per cycle per second and is expressed in Hertz. The audible range of sound is between 20 to 20 000 Hz.
