The sounds associated with jet planes measure between 120 and 140 decibels. Any sound above 85 decibels has the potential to cause hearing damage, especially with frequent or prolonged exposure. Wearing ear protection and limiting exposure to loud sounds is the best way to protect against noise-in...
The bel is named for Alexander Graham Bell (1847-1922). The decibel is not an SI unit, though the use of the decibel with SI units is sanctioned by the CIPM.² The symbol for the decibel was originally “db”, but over time the influence of the SI usage rules has been so strong...
Step-by-Step Solution:1. Definition of Decibel: A decibel (dB) is a unit of measurement that expresses the ratio of two values, commonly used to measure sound intensity. 2. Logarithmic Nature
What is an A-weighted decibel (dBA or dB(A))? A-weighted decibel (dBA or dB(A)) is an expression of the relative loudness ofsoundsas perceived by the human ear. A-weighting gives more value to frequencies in the middle of human hearing and less value to frequencies at the edges as...

What is a Decibel? A decibel (dB) is simply a measurement of how loud a noise is. Think of dB as the volume control on your stereo. A quiet home will register at about 40 dB compared to a jet engine at around 130 dB. Decibels are not measured on a linear scale. A good rule of...
Decibels can also be impacted by factors like air pressure and what kind of medium the sound is traveling through. For example, a sound traveling through water will have a different decibel measurement than a sound traveling through the air. While the primary difference between hertz and decibels...
