摘要： An earpiece includes an Ambient Sound Microphone (ASM) configured to measure a background noise signal, an Ear Canal Receiver (ECR) configured to deliver audio to an ear canal, and an optional Ear Canal Microphone (ECM) configured to convert an internal sound within an ear canal of a user to an internal sound signal, and a processor operatively coupled to the ASM, the ECR and optionally the ECM. Note, internal sounds can also include residual background noise related to ambient sounds in the environment. The processor is configured to maintain a natural audio level based on a combined measurement of the background noise signal and the internal sound signal.

摘要： Method of dynamically adapting user volume input range on mobile device having global volume range starts by receiving a volume input selection from a user that is level included in user volume input range. User volume input range is a portion of global volume range. Device's processor then detects ambient noise level surrounding device and adjusts user volume input range from current portion of global volume range to different portion of global volume range based on detected ambient noise level. Volume input selection remains at the same level included in user volume input range after user volume input range is adjusted. Processor may identify sound profile that corresponds to ambient noise level being detected and adjusts user volume input range to a different portion of the global volume range based on identified sound profile. Other embodiments are also described.
