A device is disclosed, the device comprising a least one microphone, at least one output audio transducer driver, at least one processor, a storage comprising a set of instructions executed locally, wherein the set of instructions causes the processor to: continuously measure an ambient sound pressure level when the device is an on state, calculate a sound pressure level of the output audio transducer driver when the output audio transducer is active, combine the two sound pressure levels into a total sound pressure level.

Continuous sound pressure level monitoring

Radio terminal equipment of a communication system, the communication system comprising one or more secondary units coupled to the radio terminal equipment, the radio terminal equipment comprising: means for receiving information on audio characteristics optimising an audio signal of the secondary unit, means for converting the audio characteristics information into a form of an audio control algorithm used in the radio terminal equipment for performing a secondary unit audio control algorithm, means for optimising an audio signal of the secondary unit by using the secondary unit audio control algorithm.
