Title: BABY HEARING PROTECTION SYSTEM AND METHOD FOR USE IN BABY CARRIAGE
Abstract:
Provided is a baby hearing protection system (10) for use in a baby carriage (1). The baby carriage (1) comprises a first sound sensor (11), an electric motor (12), an electronic vent valve (13), a second sound sensor (14), a projection unit (15) and a memory (16) respectively connected to a microprocessor (17) via a data bus. The system (10) comprises: a noise monitoring module (101) for detecting and determining whether the ambient noise is greater than a first sound intensity value via the first sound sensor (11); a hearing protection module (102) for controlling the electric motor (12) to enable noise reduction cloth (3) to be unrolled and cover an opening of the baby carriage (1) when the ambient noise is greater than the first sound intensity value and for controlling the opening of the electronic vent valve (13); a crying detection module (103) for monitoring the baby's crying via the second sound sensor (14) and controlling the projection unit (15) to project cartoon pictures to a lower surface of the noise reduction cloth (3); and a protection removing module (104) for controlling the rolling-up of the noise reduction cloth (3) when the ambient noise is less than a second sound intensity value. Further provided is a baby hearing protection method. The system and the method can applied to reduce the intensity of ambient noise so as to protect a baby against hearing impairment caused by the ambient noise.
