Decibel sound.

Sound level meter or SPL meter is a device that measures the sound pressure level (SPL) of sound waves in decibels (dB-SPL) units. SPL meter is used to test and measure the loudness of the sound waves and for noise pollution monitoring. The unit for measuring of sound pressure level is pascal (Pa) and in logarithmic scale the dB-SPL is used.Sound intensity is measured in decibels (dB); the unit A-weighted dB (dBA) is used to indicate how humans hear a given sound. Zero dBA is considered the point at which a person begins to hear sound. A soft whisper at 3 feet equals 30 dBA, a busy freeway at 50 feet is around 80 dBA, and a chain saw can reach 110 dBA or more at operating distance.The decibel scale measures how loud a sound is. Decibels are used to quantify sound intensity in the context of music. The decibel scale is based on a logarithm with base ten. Loud noise is very damaging to hearing. Using the logarithm of the bel, we can get the power ratio in decibels (remember that the bel compares values to a ratio of …Putting those two things together, a 100-fold increase in sound intensity would give a 20dB increase on our sound meter and feel like a quadrupling in loudness. So a sound of 100dB is 90dB louder than a sound of 10dB, which is a billion times more intense and 2×2×2×2×2×2×2×2×2 = 2 9 or roughly 500 times louder.

Amplitude is measured in decibels (dB), which refer to the sound pressure level or intensity. The lower threshold of human hearing is 0 dB at 1kHz. Moderate levels of sound (a normal speaking voice, for example) are under 60 dB. Relatively loud sounds, like that of a vacuum cleaner, measure around 70 dB.
