The loudest sounds made by an animal are unidirectional clicks produced by sperm whales (Physeter macrocephalus), which they use for echolocation while hunting for prey in the low-light ocean depths.

Decibels are commonly used in electronic systems that include RF, audio, and more recently, signal integrity. While many engineers already think in decibels, if you mostly work in the time domain, you ...

One of the most difficult-to-understand terms for newcomers (and even experienced enthusiasts) in audio and sound reproduction is the decibel, partly because it’s a measure of relative intensity or ...

Sperm whales produce clicking sounds that reach source levels of 236 dB re 1 micropascal at one meter, making them the loudest known biological sound on Earth. These brief, powerful pulses travel ...

The decibel is as commonly used in audio circles as the minute or the mile is in general usage. A superficial understanding of the decibel can hinder the study of the science of sound and be a barrier ...

For those looking to gain a deeper understanding of how audio works, whether to make better-informed decisions or simply for the sake of curiosity, it's useful to lay down some ground rules that ...

Editor's Note: We have strived to maintain accessibility in our Bring Science Home activities by limiting the required technology. We recognize technology is now more widely available than it was when ...

A decibel (dB) is a unit used to measure how loud a sound is. The louder the sound, the higher the decibel number. Sounds are made when something vibrates, creating sound waves that travel through the ...
