Problems solved by technology

According to statistics, noise will reduce labor productivity by 10-50%. With the increase of noise, the error rate will increase.
It can be seen that noise will distract people's attention, resulting in slow response, easy fatigue, decreased work efficiency and increased error rate.

Abstract

The invention provides a portable multifunctional noise detector, belonging to the field of hardware tool manufacturing. The portable multifunctional noise detector comprises an outer shell, a liquid crystal display screen, a control panel, a condenser microphone, an AC signal output interface and a storage battery, wherein the condenser microphone is installed on the outer shell, the liquid crystal display screen is installed on the front surface of the outer shell, the control panel is installed below the liquid crystal display screen, the AC signal output interface is installed on the side surface of the outer shell, the back surface of the outer shell is provided with the storage battery, and the liquid crystal display screen, the control panel, the condenser microphone and the AC signal output interface are electrically connected through lead wires. Through the cooperative use of the outer shell, the liquid crystal display screen, the control panel, the condenser microphone, the AC signal output interface and the storage battery, the portable multifunctional noise detector can be used for measuring noise volume when the noise is made and can output relevant data.

Description

Technical field [0001] The invention relates to the field of hardware tool manufacturing, in particular to a portable multifunctional noise detector. Background technique [0002] Noise refers to the sound produced when the sounding body vibrates irregularly. Sound is produced by the vibration of an object and propagates in a certain medium in the form of waves. Generally speaking, noise pollution refers to man-made. From a physiological point of view, all sounds that interfere with people's rest, study and work, and the sounds you want to hear, that is, unwanted sounds, are collectively called noise. When noise has adverse effects on people and the surrounding environment, noise pollution is formed. Since the industrial revolution, the creation and use of various machinery and equipment has brought prosperity and progress to mankind, but at the same time it has also produced more and more noise. Noise not only causes damage to hearing, but also induces a variety of cancer-ca...
