Description

Technical Field

[0001] The utility model relates to a hardware architecture, and in particular to an auxiliary listening Bluetooth earplug. Background Art

[0002] Traditional hearing-assistive Bluetooth earplugs are worn by people with mild hearing loss. They collect external sounds, perform computational processing, and gain amplification to compensate for hearing loss, thereby restoring hearing loss to a normal range. However, for traditional hearing-assistive earplugs on the market, when the hearing-assist function is turned on, the sounds from all sound sources collected will be amplified, which will cause the user's own voice to be amplified at the same time, weakening the amplification effect of the hearing aid on external sounds during a two-way conversation. At the same time, amplifying one's own voice will produce a delay effect and a stethoscope effect, which greatly affects the user's experience.
