02. BOACH acoustic electronic product testing services
· Macroscopic performance test of sound-absorbing materials and 9 microscopic parameter tests:
· Material sound absorption/sound insulation testing, porous material density and porosity testing;
· Support material sound absorption and sound insulation testing based on impedance tube testing standards to obtain sound absorption/sound insulation curves that change with frequency;
· Mainly test material macroscopic Mainly parameters;
· Material/sample flow resistivity, viscosity characteristic factor, thermal characteristic factor and tortuosity test;
· Foam materials need to detect modulus, which can be tested through the material loss factor test bench;
· Currently testable materials: foam materials, Felt.
· Currently detectable materials: fiber cotton, metal fiber, foamed ceramics, etc.
· Waterproof sound-permeable membrane insertion loss and acoustic impedance performance testing:
· Frequency response/distortion test of waterproof sound-permeable membrane;
· Verify whether the performance of waterproof sound-permeable membrane meets the index requirements;
· The index is mainly to evaluate the insertion loss.
· Acquire the acoustic impedance of the waterproof sound-permeable membrane;
· Use a micro-flow sensor to obtain the flow rate and flow rate;
· Convert the acoustic impedance characteristics of the membrane through an internal program.
· Speaker frequency response and distortion characteristics test:
· Performance testing and calibration of power amplifiers/laptops:
· Obtain the frequency response characteristics of the speaker and evaluate based on a distance of 1m;
· Based on the single frequency signal, evaluate the distortion characteristics of the speaker respectively and evaluate whether it meets the actual requirements of the product;
· Power amplifier performance testing and calibration: distortion and distortion performance testing;
· Laptop performance calibration: used to evaluate the consistency of clinical and other special application scenarios with professional acoustic test results.
