Measurement condenser microphones, also known as standard microphones, are used to measure electro-acoustic devices and to measure environmental noise. Measuring the bandwidth of the microphone is flat, and the stability is good. When the ambient temperature changes, the measuring microphone index can remain stable. Therefore, the test microphone is an artifact for the performance of the tuner and a small assistant in the acoustic division. Measurement & Test Microphones are mainly classified according to microphone power supply, interface, price, calibration, diameter of head, and support for smart phones. The common standard microphones in the domestic market (note that they are common, do not fight prices, and are used for sea) include micw M215, micw M416, micw i436, superlux ECM888B, and superlux ECM999. Only the micw i436 shows that professional-grade measuring microphones used on mobile phones are rare. Today, this love thinking iSV1600 test wheat, whether it is Android or Apple iOS support is very perfect, and comes with a "perfect noise" APP for users to measure the use of sound pressure.
The iSV1600 test microphone is a hardware device tailored by Zhejiang Love Thinking Instrument Co., Ltd. for "Perfect Noise" APP. The main purpose of the iSV1600 test microphone is to measure the noise with the mobile phone APP and improve the accuracy of the noise measurement. In addition, it can also be used for audio recording in applications where high sound quality is required.
Love thinking iSV1600 test microphone and micw i436 have a fight in the mini body above, my finger to hang this "waterproof warehouse" (outdoor sports enthusiasts may contact more waterproof warehouse, it is suitable for loading pills, letters , fire, etc.) is the packaging of the iSV1600 test microphone. The aluminum material is delicate and compact, and it is equipped with a key hanging buckle that can be directly attached to your key ring. When not in use, it becomes a small decoration on your keychain. When using, open the package can be used anytime, anywhere, easy to carry, do not take up places.
Unscrew the waterproof bin, you see the microphone itself, love thinking iSV1600 test microphone has a unique metal texture, beautiful shape, small and exquisite, standard four (core or pole) plug, can be connected with mobile phones and other smart devices.
The standard quarter-inch pickup head (diameter ø 7mm) can be calibrated directly with an audio calibrator. The appearance of the metal is accompanied by silver-white metal packaging. The feeling of tallness is so strong that people can hardly put it down!
When it's in front of you, you can't believe it. It's actually a microphone? Because it's really too mini, it's a bit similar to Xiaomi's introduction of Mi Key, a 3.5mm headphone plug (four-pole connector).
The top of the microphone is where the pickup head is located. The outermost layer is a metal protective cover with an outer diameter of φ7 mm. The protective cover has a grid opening, which is the pickup of sound waves. Sensitivity level: -32dB ± 3dB (IV/Pa is reference 0dB); frequency range: 50Hz ~ 10kHz ± 2db, 20Hz ~ 20kHz ± 4dB.
The iSV1600 test microphone is an electro-acoustic transducer that can measure the sound signal with a mobile phone or tablet computer and a noise measurement app. Simply plug the iSV1600 test microphone into the phone jack of your mobile phone or tablet and open the "Perfect Noise" APP. It can read the data of the measured acoustic signal, and also can realize sound level integral measurement, statistical measurement, real-time 1/1 OCT, 1/3 OCT, FFT and other functions.
Before introducing the "Perfect Noise" APP, we must emphasize that the iSV1600 test microphone is also suitable for other audio-related software, such as interview recordings: Luci, CideoFX Live, Tascam, fourtrack (free), etc.; Voice recording: Luci, FiRe, Hindenburg, Dragon, et al.; Measurement Analysis: Analyzer, SigScope Pro, Faber Acoustical, RT30, RT60, soundmeter; and the like.
"Perfect Noise" APP is a free sound level measurement and noise spectrum analysis software developed by Hangzhou Aihua Instrument Co., Ltd. Through this application software, even using the phone's built-in microphone can also monitor the environmental noise. Many DIY people in the PC industry like to use the "Perfect Noise" APP to test the noise situation of the computer chassis, although not extremely accurate, But it also reflects the surrounding noise facts. Once the Perfect Noise APP is combined with the iSV1600 test microphone, they become a professional artifact.
"Perfect noise" APP settings are very rich, the signal input, sampling frequency, line number, overlap rate, spectrum mode, screen refresh time, coordinate axis parameters, colors and other related content can be operated in the APP "settings" page, management.
The iSV1600 Test Microphone is also a calibratable microphone that requires additional calibration hardware "iSV1310 calibration source". The iSV1310 calibration source supports calibration of 1/4-inch sound level meters. The iSV1310 calibration sound source is perfectly matched with the iSV1610 test microphone, and the sound level is calibrated through the “perfect noise†of the mobile phone APP, making the measurement of smart devices such as mobile phones more accurate!
The "Perfect Noise" APP has three main interface tabs: SINGLE, GRAPH, and LIST. The setup parameters are: 1. Lin: the current number of FFT sampling lines; 2. Window functions: There are seven types of total, which are obvious in the spectrum diagram interface (Rec. is a rectangular window, Tap. is a trapezoidal window, Tri. triangular window, and Han. For Hanning window, Ham. for Hamming window, Bla. for Blackman window, and Fla. for flat-top window); 3. Samp. for sampling rate; 4. Wei. For weighting method, it is divided into A. , C, Z three weighting methods; 5, @ Max shows the frequency of the maximum point and its value; "perfect noise" APP there is a description page to help users skilled use of the software.
Summary: The combination of the "Perfect Noise" APP+ iSV1600 Test and Mai-Thinking breaks the boundaries between civil and professional, making everyday noise measurements even easier, even in professional acoustic field measurements. The seamless support for Android and Apple's mobile phone systems has earned it respect from the industry; knowing that professional-grade measuring microphones, including the micw i436, may not be able to perfectly support all Android phones. The most important thing is that its price is still very cheap, the microphone is less than two hundred dollars, APP is completely free. The boat that measures the friendship between the microphone “light cavalry†and the big players in the survey industry seems to be turning over.
