System and methods for processing audio signals are disclosed. In one implementation, a system may comprise a wearable camera configured to capture images from an environment of a user; a microphone; and a processor.

The invention discloses a method for realizing hearing aid function based on Bluetooth headset chip and a Bluetooth headset: the common Bluetooth headset chip software of Bluetooth headset is upgraded to a specific Bluetooth headset chip with hearing aid function by a hearing loss correction software; a hearing aid algorithm module is embedded into the development kit of the common Bluetooth headset chip in the form of software library by the hearing loss correction software, so that the common Bluetooth headset chip has the hearing aid function only by software upgrade; after being processed by the hearing aid algorithm module, a sound signal is output to a hearing-impaired user, so that the hearing-impaired user can use the common Bluetooth headset to realize the hearing aid function. For the Bluetooth headset, a special hearing aid chip does not need to be installed or any change does not need to be made to the headset hardwares, and the function and price can meet the needs of hearing-impaired users, so that the hearing impaired users can enjoy great convenience from such a Bluetooth headset without buying expensive special hearing aid.
