sound pressure

The length of the zone adjacent to a transducer in which fluctuations in sound pressure occur is mostly affected by: A.

While physical hearing protection can reduce sound pressure levels, they do not adequately prevent NIHL in very noisy environments.

As the sound pressure level increases, the range of particle rate decreases, and the relative variation trend turns to be stable.

The received echo wave's amplitude is keeping with the theoretical sound pressure value. So the result of experiment is credibly.

Finally, as an application of time series analysis, the short-term prediction to the sound pressure oscillation is presented and discussed.

This powerful bass system is capable of delivering high sound pressure levels with very low distortion over sustained periods.

The structure parameters are optimized theoretically. The sensitivity and output sound pressure of this device are calculated.

Non-linear distortion - intermodulation, harmonic, clipping - affects primarily the maximum tolerable sound pressure level.

ASW can be evenly broadened to a wide range by adjust the sound pressure level of central loudspeaker.

The greater sound pressure and energy are more favorable flow of particles.

It is also insightful to examine how the sound pressure level varies with jet velocity as the function of frequency.

Dynamic Pressure Sensors can measure a wide range of varying high intensity sound pressure and high level dynamic pressure events.

upbuild the signal model for ship noise , deduce the relationship between sound pressure and particle velocity in plane wave.

Acoustics - Hearing protectors - Part 4 : measurement of effective sound pressure levels for level-dependent sound-restoration ear-muffs.

The vibration is characterized by the virtual value of acceleration, and the noise is indicated by the sound-pressure-level.

The most common usage is as a measure of relative sound pressure in short, loudness.

And both the vortex-shedding frequency and the sound pressure level will increase while raise the incoming flow velocity.

If you use any condenser mic, it is crucial to realize that the sound pressure may hurt the fragile condenser diaphragm.

It is clearly observed from the graph that the sound pressure level has a significant influence on the particle rate.

at last, the wave superposition method was applied to reconstruct the sound field based on the expanded sound pressure.

A stereo effect is achieved through differences in sound pressure level between two microphones.

Results The sound pressure is superposed by normal sound wave and higher vibration in phase.

the machines radiating sound as sound sources, and the sound pressure inspirits the hull.

There is a remarkably wide range of frequencies and sound pressure levels over which the human ear can detect.

Measurement of sound pressure level for sound sign.

Because the kick drum sound pressure and transient is strong, I highly recommend a dynamic mic.

It involves the use of multi-sensor information such as vibration, sound, pressure and temperature, to detect and identify engine faults.

The reason for this is that bubble size increases with the decrease of the sound pressure level.

The audible sound pressure range is from 0 dB to 120 dB.
