Loud sounds produce larger sound waves and bigger vibrations, which can damage the hair cells in the cochlea. This damage usually accumulates slowly and painlessly, so you might not notice it happening. However, noise-induced hearing loss is permanent. Any noise above 85 decibels has the potenti...
A certain sound level is increased by an additional 20 dB. By how much does its intensity increase? Explain how to solve this without the use of a calculator. A 60-dB sound wave hits a boundary and transmits 88.8% of its intensity into the...
What decibel level is safe? What is the difference between threshold and maximal stimulus? What is the normal range for ESR? What is the difference between an absolute and subliminal threshold? What is the intensity of a 70 dB sound?

Decibel (dB) definition Decibel (Symbol: dB) is a logarithmic unit that indicates ratio or gain. Decibel is used to indicate the level of acoustic waves and electronic signals. The logarithmic scale can describe very big or very small numbers with shorter notation. ...
What is a Decibel?The decibel is the common measure of sound intensity and radio signal strength. Although it has never been ratified by any governing standards body, its suitability to measuring ratios and losses has led to widespread adoption of the decibel in industry and research. Although ...
B. The street. C. The rock concert. D. The factory. ( B )49. Which of the following statements is NOT true according to the passage? A. Many things can cause noise. B. A decibel is a unit to measure sound. C. Sounds of over 120 decibels must be from traffic. D. Some sounds...
What is molecular pathology procedure, level 7? What is physical contamination? What is titre in titration? What is an experimental procedure? What are the principles of confidentiality? What are the characteristics of science? What decibel level is safe?
The most commonly used unit of measure for sound is the decibel. Unlike units like meters or kilos, of which most people vaguely know the comparative length or weight, decibels are much more difficult to measure without a Sound Level Meter. Graham Bell, a Scotsman whose surname was honored ...
Decibels: Not Just for Sound Intensity Level The Decibel Scale Noise-Induced Hearing Loss What Are Decibels? Decibels (abbreviated dB) are the units used to measure the relative intensity of a sound. The decibel unit of measurement is a little odd because the human ear is incredibly sensit...
