1. A method for providing an audible indication to an operator of a vehicle at an audible volume comprising the steps of:
- determining an operational state of the vehicle; and
varying the audible volume at which the audible indication is provided to the operator based at least in part on said determined operational state of the vehicle.

Abstract
A system and method for a vehicle adjusts the volume of an audible indication. An operational state of the vehicle is determined. The audible volume at which the audible indication is provided to the operator is varied based at least in part on said determined operational state of the vehicle.

11. A method for providing an aural warning to an operator of an aircraft comprising:
-
predicting an ambient noise level on a flight deck of an aircraft based on at least one of an airspeed, an elevator position, an aileron position, a rudder position, a trim, a flap position, a slat position, an airbrake position, a landing gear position, engine throttle, an altitude of the aircraft, barometric pressure, airspeed, turbulence, temperature, and humidity; detecting an aural warning condition of the aircraft; providing an aural warning signal to an audio device mounted within the flight deck of the aircraft; applying a first predetermined gain to the aural warning signal such that the aural warning is emitted from the speaker and provided to the operator at a first volume if said predicted ambient noise level is a first ambient noise level; and applying a second predetermined gain to the aural warning signal such that the aural warning is emitted from the audio device speaker and provided to the operator at a second volume if said predicted ambient noise level is a second ambient noise level. - View Dependent Claims (12, 13, 14, 15)

16. An avionics system comprising:
-
an audio device mounted on a flight deck of an aircraft to provide an audible indication to an operator of the aircraft; a gain amplifier coupled to the audio device to provide a gain to an audio signal provided to the speaker; and a processor in operable communication with the audio device and the gain amplifier, the processor being configured to; determine an operational state of the aircraft based on at least one of a configuration of the aircraft and an atmospheric condition; and vary the audible volume at which the audible indication is provided to the operator based at least in part on said determined operational state of the aircraft. - View Dependent Claims (17, 18, 19, 20)
