A moo box. The moo box or moo can is a toy or a souvenir, also used as a hearing test.When turned upside down, it produces a noise that resembles the mooing of a cow.The toy can be configured to create other animal sounds such as the meow of a cat, the chirp of a bird, or the bleat of a sheep.
Choosing the most appropriate hearing protection device, both with appropriate level of attenuation and appropriate fit for the individual. [5] Ideally, the device should limit the sound intensity that reaches the ear to levels below 85 dBA. If the attenuation does not limit the noise levels to that level, other alternatives should be sought.
Noise measurement can also be part of a test procedure using white noise, or some other specialized form of test signal.In audio systems and broadcasting, specific methods are used to obtain subjectively valid results in order that different devices and signal paths may be compared regardless of the inconsistent spectral distribution and temporal properties of the noise that they generate.

An impulse noise filter can enhance the quality of noisy signals to achieve robustness in pattern recognition and adaptive control systems. A classic filter used to remove impulse noise is the median filter, at the expense of signal degradation. Thus it's quite common to get better performing impulse noise filters with model-based systems ...
Threshold equalizing noise (TEN) test; Masking level difference (MLD) test; Psychoacoustic (or psychophysical) tuning curve test; Speech audiometry is a diagnostic hearing test designed to test word or speech recognition. It has become a fundamental tool in hearing-loss assessment.
Hearing conservation programs [1] are programs that should reduce the risk of hearing loss due to hazardous noise exposure, if implemented correctly and with high quality. . Hearing conservation programs require knowledge about risk factors such as noise and ototoxicity, hearing, hearing loss, protective measures to prevent hearing loss at home, in school, at work, in the military and, and at ...
A substantial part of this noise results from the use of power tools, which can produce dangerous levels of noise by themselves. [6] Although the loudness of power tools may be quite apparent to those using them, the actual level of noise produced was mostly unreported and not available easily in an online reference.
