Problems solved by technology
[0003] However, the existing noise detection device still has certain defects in use, because the detection device is easy to cause inaccurate detection results due to the loss of the transmission medium and sound waves during transmission during the detection process, and the existing noise detection device also has the disadvantage of being portable. Convenient, can't be carried around

The invention discloses a high-precision noise detection device. The device comprises a cover ring, a detection device, clamping grooves, clamping buckles, a fixed groove, a protrusion, sound holes, a detection instrument, a button, a storage groove, a receiving device, an upper arc block, a touch point and a lower arc block. The high-precision noise detection device has the advantages that the noise detection instrument is installed inside the cover ring, so that the noise detection device has the advantages of being small in size and convenient to carry; by installing the receiving device used for receiving noise inside the detection device, the receiving device is closely attached to the inner wall of the storage groove and is close to the portion near the sound hole, the receiving device is constituted by the upper arc block, the lower arc block and the touch point, the upper arc block and the lower arc block are in a fan structure and cover the contact point, so that when the noise is transmitted to the touch point through the sound holes, the noise is directly transmitted to the touch point through the fan structure constituted by the upper arc block and the lower arc block and detected by the detection instrument, the situation that the sound is weakened in the sound transmitting process due to a transmission medium is effectively avoided, and the precision of noise detection is effectively improved.
Description
technical field [0001] The invention relates to a high-precision noise detection device, which belongs to the field of noise detection. Background technique [0002] With the development and progress of science and technology, people's daily life, production and other activities will generate noise. Noise will not only affect people's physical and mental health, but also interfere with people's daily life. Therefore, noise detection is very important. The common monitoring index of noise is the intensity of the noise, that is, the sound pressure in the sound field, and the characteristic of the noise is the various frequency components of the sound pressure. Noise measurement instruments mainly include: sound level meter, frequency analyzer, real-time analyzer, sound intensity analyzer, noise level analyzer, noise dosimeter, automatic recorder, tape recorder. [0003] However, the existing noise detection device still has certain defects in use, because the detection device...
