Ambient noise level is measured with a sound level meter. [4] It is usually measured in dB relative to a reference pressure of 0.00002 Pa, i.e., 20 μPa (micropascals) in SI units. [5] This is because 20 μPa is the faintest sound the human ear can detect. [5] A pascal is a newton per square meter. The centimeter-gram-second system of units ...
The first California was designed in consultation with the Los Angeles Police Department Traffic Division to modify the Moto Guzzi Ambassador, the winner of the tender for the supply of vehicles for the L.A.P.D. [1] [2] The initial idea was to develop a motorcycle that could participate in a tender called for the Italian Police forces at the ...

Noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks. While noise and vibration can be readily measured, harshness is a subjective quality, and is measured either via jury evaluations, or with analytical ...
Sound exposure level (SEL) is a logarithmic measure of the sound exposure of a sound relative to a reference value. Sound exposure level, denoted L E and measured in dB , is defined by [ 1 ]
Signal-to-noise ratio (SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. SNR is defined as the ratio of signal power to noise power, often expressed in decibels. A ratio higher than 1:1 (greater than 0 dB) indicates more signal than noise.
This equation works as an inverse, exponential, relationship. As the industrial noise intensity increases, the allotted exposure time, to still remain safe, decreases. Thus, a worker exposed to a noise level of 100 decibels for 15 minutes would be at the same risk level as a worker exposed to 85 decibels for 8 hours. [2]
The engine is a transverse-mounted 16-valve inline-four with a displacement of 1,352 cc (82.5 cu in). It has variable valve timing, derived from a Mitsubishi Motors car engine, which allows the phasing of the intake camshaft to be advanced by up to 24°. This continuous alteration happens progressively as the rpm rise and fall.
