1. Select high-performance sensors

The sensor is one of the core components of the pipe leakage audiometer, which directly affects the accuracy and sensitivity of the detection results. The selection of high-performance sensors, such as microphones, piezoelectric crystals, etc., can effectively improve the instrument's ability to collect noise and vibration signals, which in turn improves detection accuracy and sensitivity.

Through the application of advanced algorithms and data processing techniques, such as wavelet transform, neural network, etc., the collected noise and vibration data can be analyzed and processed in depth, so as to better extract the useful feature information and improve the instrument's ability to identify the leakage point.

1. Optimize the structure and design of the instrument

Optimizing the structure and design of the pipe leakage listening instrument can make it closer to the actual situation and improve the detection accuracy and sensitivity. For example, the design of the appropriate microphone and pickup position, in order to better capture the noise and vibration signals inside the pipeline; the use of anti-noise, vibration damping and other measures, in order to reduce the impact of external interference on the detection results.

IV. Precautions in practical application and cooperation with other detection methods

1. Precautions in practical application

In the application of pipeline leakage listening instrument, need to pay attention to the following points:

(1) Ensure that the instrument is in good working condition, regular maintenance and repair to ensure its accuracy and sensitivity.

(2) When carrying out the detection, minimize the interference of other noise and vibration sources, such as traffic and machinery.

(3) For large pipelines or complex environments, a combination of multiple detection methods can be used to improve detection efficiency and accuracy.

1. Cooperation with other detection methods

Pipeline leakage listening device can be used in conjunction with other detection methods in order to better solve the problem of pipeline leakage. For example:

(1) with the pressure test: by applying a certain pressure to the pipe inside the water or gas, and at the same time use the pipe leakage audiometer to detect any leakage or leakage sound to determine the location of the leakage.

(2) with the tracer test: add tracer to the pipe, and then use the pipe leakage listening device to detect the sound of tracer leakage to determine the location of the leak.
