Abstract
Abstract A communication device (10) measures and compares (16,18) the ambient sound level of its environment. When the current ambient sound level exceeds a given threshold (52) the communication device automatically transmits (38) an information signal (44). Optionally, the communication devices's volume is also adjusted (26).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
92 words
A communication device, comprising: input means for determining ambient sound level; comparison means responsive to the input means for comparing said ambient sound level to a threshold level; transmission means responsive to the comparison means for automatically transmitting an information signal related to the ambient sound when the ambient sound level exceeds the threshold; receiver means coupled to the transmission means for receiving an information signal; and means for automatically adjusting the volume level of the receiver means to a predetermined level in response to the ambient sound level exceeding the threshold.
Claim 2
Dependent Claim
92 words
A communication device, comprising: input means for determining ambient sound level; comparison means responsive to the input means for comparing said ambient sound level to a threshold level; transmission means responsive to the comparison means for automatically transmitting an information signal related to the ambient sound when the ambient sound level exceeds the threshold; receiver means coupled to the transmission means for receiving an information signal; and means for automatically adjusting the volume level of the receiver means to a predetermined level in response to the ambient sound level exceeding the threshold.
Claim 3
Dependent Claim
28 words
The communication device of claim 1 wherein the input means for determining ambient sound level comprises means for determining ambient sound energy residing in an audible frequency band.
Claim 4
Dependent Claim
28 words
The communication device of claim 1 wherein the input means for determining ambient sound level comprises means for determining ambient noise energy residing in a predetermined frequency band.
Claim 5
Dependent Claim
90 words
In a communication device, a method for ambient sound level controlled transmissions, comprising the steps of: (a) determining the ambient sound level; (b) comparing the ambient sound level to a predetermined stored level; (c) transmitting an information signal related to the ambient sound when it is determined that the ambient sound level has exceeded a predetermined threshold; (d) receiving an information signal; and (e) adjusting the volume level of the received information signal to a predetermined level when it is determined that the ambient sound level has exceeded the threshold.
Claim 6
Dependent Claim
90 words
In a communication device, a method for ambient sound level controlled transmissions, comprising the steps of: (a) determining the ambient sound level; (b) comparing the ambient sound level to a predetermined stored level; (c) transmitting an information signal related to the ambient sound when it is determined that the ambient sound level has exceeded a predetermined threshold; (d) receiving an information signal; and (e) adjusting the volume level of the received information signal to a predetermined level when it is determined that the ambient sound level has exceeded the threshold.
