Abstract

The present invention discloses a long-distance sound amplification method, device, system, storage medium and intelligent device; the method includes: acquiring first sound information through a first sound pickup device and second sound information through a second sound pickup device; A sound information filtering and amplification process to obtain the first sound amplified signal, and performing differential amplification processing on the first sound information and the second sound information to obtain the first differentially amplified sound signal; performing adjustable gain amplification on the first differentially amplified sound signal Processing: differentially amplifying the first differentially amplified sound signal after the adjustable gain amplification and the first sound amplified signal to obtain a second differentially amplified sound signal; performing volume control and power amplification on the second differentially amplified sound signal to obtain an output sound signal . It is ensured that when listening to the sound directly facing in the distance, it will not be covered by the nearby sound, thereby solving the problem of difficulty in monitoring the far-end sound signal.

Description

technical field [0001] The present invention relates to the technical field of signal processing, in particular to a long-distance sound amplification method, device, system, storage medium and intelligent equipment. Background technique [0002] In some application scenarios in the fields of safety production, anti-terrorism, and reconnaissance, it is necessary to monitor the sound of a specific area in the distance (for example, 100 meters away), but it is easily covered by loud sounds in the near field (sound masking effect). In addition, due to the high gain of the sound monitoring equipment, self-excited howling is easy to occur when the signal of certain frequencies generates positive feedback. Therefore, in the prior art, when monitoring the far-end audio signal, there is a problem that monitoring is relatively difficult. Contents of the invention [0003] The main purpose of the present invention is to provide a long-distance sound amplification method, device, sy...
