Abstract

The invention discloses a high-performance sound level meter based on an ANDROID operating system. The sound level meter comprises a housing, wherein the top of the housing is provided with a microphone, the interior of the housing is provided with an ANDROID mainboard, a power module and an analog collection board, the outer side of the housing is fixedly provided with a man-machine interaction module, and the microphone is electrically connected with the analog collection board; and the analog acquisition board, the power supply module and the man-machine interaction module are electrically connected with the ANDROID mainboard. The meter is advantaged in that a technical problem that an original sound level meter is limited in operation function is solved, the ANDROID mainboard is arranged in the sound level meter, collected data of multiple channels can be processed at the same time, the sound level meter can be applied to architectural acoustics measurement, hall tone quality measurement, sound power measurement and the like, the application range is wide, an ANDROID system is integrated, and the function is convenient to add.

Description

technical field [0001] The invention relates to the technical field of noise testing equipment, in particular to a high-performance sound level meter based on an ANDROID operating system. Background technique [0002] With the continuous improvement of people's living standards, noise hazards have been paid more and more attention. The sound level meter is the main equipment for noise measurement, it has the characteristics of small size, easy to carry, and high measurement accuracy. Existing sound level meters mainly use single-chip microcomputers as logic processors, cooperate with DSP to do calculation processing, and realize noise calculation of one channel, and the calculation functions are limited. [0003] For example, Chinese patent document CN109540281A discloses "a digital display sound level meter", which includes a housing, a display, a control panel assembly and a sound wave amplifier. The upper part of the housing is provided with a connection block, the uppe...
