Bass Test|Enhance your audio testing with the Headphone Test Stand, designed for IEC711 318-4 frequency response curve analysis and ear simulator compatibility. Ideal for R&D and quality control in IoT accessories.
频率响应(FrequencyResponse): 频率所对应的灵敏度数值就是频率响应,绘制成图象就是频率响应曲线,人类听觉所能达到的范围大约在20Hz-20000Hz,目前成熟的耳机工艺都已达到了这种要求。 谐波失真(THD): 指原有频率的各种倍频的有害干扰。放大1kHZ的频率信号时会产生2kHZ的2次谐波和3kHZ及许多更高次的谐波,理论上此数...
When you browse through our headphonereviews, you’ll see we include charts showing,among other things, the measuredfrequency responseof each product we test. The frequency response displayed on our current charts is an average of the unweighted, raw responses captured by the left and right artif...
Applicant uses the speaker () in the headphone to produce a smooth and reasonably "flat" frequency response by reversing the speaker orientation. In the reversed orientation, the front side of the speaker diaphragm () faces into the headphone cup and away from the ear. The rear side of ...
The K6500 test headphones are soft and comfortable to wear. K6500 is designed with narrow frame earmuffs. Specification General Features: Frequency Response: 20Hz - 20KHz Sound Pressure Level: 91dB ± 3dBSPL(A) Impedance: 32Ω Sensitivity: ...
Frequency response: Exterior noise damping: More measurement results Measurement results for Marshall Major IV Almost every headphone we test is checked by us: In addition to determining the frequency response, the heart of our measurements, we also evaluate the effects of noise that penetrates from...

test fixture and associated power supply is additionally needed to make up a complete headphone test system. The SoundCheck ONE headphone test sequence carries out all basic headphone measurements such as frequency response, sensitivity, THD, Rub & Buzz, Perceptual Rub & Buzz, loose particles, ...
How we do this is simple: Every headphone on the production line is tested 100% for its full frequency response, left-right balance and sensitivity. We also test for THD at high SPLs to catch any buzz or rattle. Every single one. This is a very thorough set of tests. That’s how ...
