PDF Masking of speech by amplitude-modulated noise

Sounds of less than 75 decibels , even after a lengthy exposure, are unlikely to cause hearing loss. However  Normal conversation is usually about 60 decibels. Regularly being around noise that is more than 85 decibels can cause hearing loss. Which noises can affect  Human ear can perceive a very wide range of sound pressure. The softest sound a normal human ear can detect has a pressure variation of 20 micro Pascals,  In humans, sound waves funnel into the ear via the external ear Men have approximately 5 to 10 dB greater loss in the  Sound is measured in decibels (dB). A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB.

The commonly stated range of human hearing is 20 to 20,000 Hz. Under ideal laboratory conditions, humans can hear sound as low as 12 Hz and as high as 28 kHz, though the threshold increases sharply at 15 kHz in adults, corresponding to the last auditory channel of the cochlea. 2017-11-12 · Decibels are measured close-up to sounds, but the more distance you put between yourself and the source of the noise, the less intense those sound waves will be once they reach your ears. Ultimately, the best way to decide whether a sound is too loud is to use your own judgment.

Max decibels for human ear

Sound - Sound - The decibel scale: The ear mechanism is able to respond to both very small and very large pressure waves by virtue of being nonlinear; that is, it responds much more efficiently to sounds of very small amplitude than to sounds of very large amplitude. Because of the enormous nonlinearity of the ear in sensing pressure waves, a nonlinear scale is convenient in describing the How to Measure Headphone Decibels. To avoid ear damages, you should use a safe headphone volume level. To know this, it is advisable to learn how to measure headphone decibels. By measuring the decibels, you will be able to know whether the volume you are using is safe for your ears or not.

Sound level meters are instruments designed to respond to noise much like the human ear.

0 decibel does not mean that there is no sound, merely that we cannot hear it. 0 decibel is the so-called hearing threshold for the human ear. While we can hear more than 140 decibels, it is too painful for our ears and if you expose yourself to such a loud noise you are at extremely high risk of permanent damage to your hearing.

Believe it or not, the amount of time you are exposed to high decibels of sound is just as important as the rate of decibels. So, an occasional loud noise may cause you less loss then a long time of a much quieter sound. The human ear has a standard sound threshold of 120 dB, which expressed logarithmically is around 1012. This is a standard threshold, but it also depends on frequency. Loudness is a measure of sound intensity taking frequency into account, and is called a A-weighted decibel, dB(A), or a phon. The highest note of human speech is a soprano singer’s C7 (around 2048Hz) and the lowest note is the C2 of a bass singer (around 64Hz).
