Where the ambient noise level of the environment is above 45 dB SPL, a volume gain of at least 20 dB above the ambient level shall be user selectable.

In a pulse train air pressure is increased from ambient (p0) to a first level (p1) and from there repeatedly to a second level (p2) and repeatedly decreased to the first level (p1), and finally decreased to ambient (p0).

The backlight controller (126) may use the photosensor (130) to determine ambient light levels and to enable or disable the backlight (124) based only on ambient light levels.

Emergence is a temporary modification of the ambient level caused by the appearance or disappearance of a specific noise.

When the temperature returns to ambient the flap (22) flattens out and reseals the aperture (23).
