Acoustic signal processing system for mobile portable device and processing method thereof

Abstract

The invention discloses an acoustic signal processing system for a mobile portable device and a processing method thereof. The system adopts a microphone on the existing mobile portable device to collect acoustic signals on the periphery of the existing mobile device and adopts an operational unit to compute various acoustic property indexes in a present environment, displays various analysis results and patterns through a display, and gives suggestions for users according to analysis results. If the mobile portable device is provided with a communication network, the system can also transmitthe analysis results and the azimuth position of the mobile portable device to a server, and the server can predict and draw an acoustic distribution diagram in a larger zone through data fed back from all users and a geographic information system, and feed back summarized results to all the users, thereby realizing real-time monitoring, analysis and early warning on noise in a large zone.

Description

technical field [0001] The present invention relates to a signal processing method and system, in particular to an acoustic signal processing system and processing method for mobile portable equipment. Background technique [0002] Sound, especially noise, affects people's normal life, work and study. In a noisy environment, people feel irritable, distracted, fatigued, and unresponsive, which leads to reduced work and study efficiency, affects work progress, reduces work quality, and is prone to mistakes and accidents; noise interferes with people's sleep and harms people. People's physical and mental health, reduce people's quality of life. [0003] Noise not only damages people's hearing, causes hearing loss and noise-induced deafness, but also affects the nervous system, cardiovascular system, endocrine system, digestive system, vision, and intelligence to varying degrees. [0004] Long-term exposure to high-noise environments will cause the auditory organs to be consta...

Problems solved by technology

[0006] The existing methods and equipment for measuring environmental noise are mainly specialized sound level meters. Specifically, on the one hand, the development of technology in recent years has made the structure of sound level meters move from analog to digital, and the measurement dynamic range is larger , the measurement is more accurate, but because it is specialized equipment, it is expensive and difficult to maintain, it is not suitable for large-scale use, and it is even more difficult to make one for everyone
