HEARING / AUDITION
Stimulus :Various signals can be used; pure tone frequency sweep, warble tone frequency sweep, white noise and speech shaped noise are commonly used.
Speech shaped noise :A speech shaped noise is a (white) noise signal shaped as long-term normal speech over frequency. The low frequencies have a higher level than the high frequencies. At an input level of 65 dB SPL, the total sound pressure level will be 65 dB SPL, the sound pressure level at a single frequency will be lower and have different levels at different frequencies. Unlike real speech signals, white noise and speech shaped noise are steady state signals. The REIG will show the average gain for a certain input level; it does not reflect the dynamic behaviour of real speech.
Compared to white noise, speech shaped noise can be a better choice to test multi-channel non-linear instruments such as Adapto, Gaia and Atlas. The REIG will be greater for the weaker high frequencies and lower for the more intense low frequencies which are a better illustration of the gain for normal speech.

bruit de fond sonore
Mais c'est aussi le brouhaha qui me gêne pour entendre, le froissement d'un papier qui a recouvert la moitié de ta phrase, et me l'a rendu incompréhensible; ou bien c'est le bruit d'un dîner de famille, au sein duquel les voix de tous m'empêchent de comprendre la tienne. De ce Janus qu'est le bruit de fond, c'est cette face nocive qui nous gêne le plus quand on s'occupe de surdité. On le retrouve partout. Il noie l'information et c'est à cause de lui sans doute qu'un des rôles de l'oreille interne est d'accentuer, de caricaturiser presque le message signifiant pour le faire émerger de ce ***bruit de fond sonore*** qui l'accompagne toujours.
