Collective optimal listening gain system and collective optimal listening implementation method

Abstract

The invention relates to a collective optimal listening gain system and a collective optimal listening implementation method. The system comprises at least one miniature microphone and a plurality ofsound amplifying devices which are in wireless connection with the miniature microphones; the multiple sound amplifying devices are uniformly arranged above an optimal listening space at intervals; sound outlets correspond to all regions in the optimal listening space; and a plurality of sound absorption bodies are arranged above the optimal listening space. The method comprises the following steps that sound is collected by the miniature microphones and are converted into an electric signal to be wirelessly sent to the multiple sound amplifying devices; and the multiple sound amplifying devices correspondingly transmit sound waves to all the regions of the optimal listening space, meanwhile, the sound absorption bodies are used for absorbing ambient noise and whistle tones generated by the multiple sound amplifying devices, so that the whole optimal listening space forms a uniformly-propagating sound field. According to the system and the method, the uniformly-propagated sound field can be formed in the whole optimal listening space, and the highest-quality sound can be heard at any point of the optimal listening space; and a teacher can conduct teaching or tutoring at any place of a classroom as long as the teacher wears the miniature microphone.

Description

technical field [0001] The invention relates to a sound processing system and method, in particular to a collective optimal listening gain system and a collective optimal listening realization method, which are used to form a uniform sound field in public spaces such as classrooms and conference rooms. Background technique [0002] At present, the sound processing system in the classroom includes a miniature microphone and a loudspeaker device. The miniature microphone is worn on the teacher, and there is only one loudspeaker device, which is installed on the top of the front or back corner of the classroom. When in use, the miniature microphone collects the teacher's voice, transmits it to the amplifying device, and radiates it to the classroom after being amplified by the amplifying device. There are following technical defects in this sound processing system: 1, the sound field is uneven. The sound field at the loudspeaker is the strongest, and gradually weakens as the d...

AI Technical Summary

Problems solved by technology

This sound processing system has the following technical defects: 1. The sound field is uneven

In this way, on the one hand, the teacher’s voice must be loud enough when speaking, which is very difficult. On the other hand, the students who are close to the amplifying device hear very harsh voices, while the students who are far away from the amplifying device hear very small sounds, resulting in teaching effects. Difference

2. There are environmental noises and howling sounds generated by loudspeaker devices, which affect normal teaching

Such a sound processing system has the following technical defects: Since the FM receiver needs to be worn by the hearing-impaired person and connected to the hearing-impaired person's own hearing equipment every time it is used, it results in cumbersome operations and frequent plugging and unplugging. It is easy to damage the hearing equipment of the hearing-impaired person
