Measurement Microphones & Sound Level Meters

Buy high-quality measurement microphones cheaply at the Masori car audio online shop

Those who want to perform optimal sound measurements in their car will find a wide selection of measurement microphones for car hi-fi and professional audio analyses in Masori's car hi-fi online shop. These microphones are suitable for precise frequency response determinations, exact room acoustics calculations, and fine-tuning of car hi-fi systems in Audi, VW, BMW, Mercedes, SEAT, or Opel. Thanks to the latest technology and various designs, they offer both beginners and experienced users the opportunity to take their car sound environment to the next level. Installation is often done with suitable accessories as a plug & play solution to easily complement existing car audio setups.

Wide portfolio of renowned brands for precise audio capture

To meet the variety of different requirements, Masori offers measurement microphones from renowned manufacturers such as Audiocontrol, ETON, Gladen, miniDSP, and SPL Lab. Each model comes with specific performance data to carry out various acoustic measurements in the car:

• Audiocontrol models: Mostly with a frequency response of 20 Hz to 20 kHz and 50 Ohm impedance, ideal for precise standing wave analyses in vehicle interiors.
• ETON variants: Typically -38 dBV/Pa sensitivity and flat frequency response for detailed sound measurements across the full car audio spectrum.
• Gladen Microphones: 18 Hz to 22 kHz measurement range and 80 Ohm impedance, designed for noise reduction in hi-fi-optimized car audio setups.
• miniDSP models: 19 Hz to 20 kHz bandwidth, variable sensitivity, modularly expandable for individual vehicle acoustics projects.
• SPL Lab Solutions: 16 Hz to 25 kHz frequency range, excellent dynamics for SPL measurements and scientific research.

The different types of measurement microphones enable the recording of speaker characteristics in the car, the tuning of crossovers, as well as the detection of peak levels. Thanks to variable connection options and compatible software, car audio systems can be individually optimized in both older and modern vehicle models.

Typical Features and Technical Data at a Glance

In all models, the combination of frequency range, impedance, and sensitivity is of enormous importance to accurately reproduce both quiet and loud sound components in the vehicle. For car sound optimizations in various vehicle types (e.g., VW Golf, BMW 3 Series, or Mercedes C-Class), measurement microphones that ensure plug-and-play integration with low impedance and universal connection standards are particularly suitable.

Installation tips, accessories, and cable management

Correct positioning and stable equipment are indispensable for car audio measurements. It is recommended to place the measurement microphone at ear level inside the vehicle to simulate very realistic listening positions. The following accessories are useful for this purpose:

• Microphone arms or stands for adjustable mounting on door, seat, or fixture.
• High-quality microphone cables with low capacitance for lossless signal.
• Pop filter or windscreen to reduce sudden air blasts at lower frequencies.
• Calibration adapter or reference tone generator to ensure the accuracy of the measurement system.

If you are unsure whether the selected measurement microphone is compatible with your car audio system, you can use Masori's AI chatbot to receive suggestions tailored specifically to your car. For further questions, our expert support team is also available to ensure a smooth integration into your car hi-fi setup. Upon request, our installation service in Frankfurt Oder can also professionally handle the installation.

Areas of application and possible sound optimizations

Measurement microphones are primarily used in cars to determine the Thiele-Small parameters of speaker components. These parameters describe, among other things, the resonance frequency, the quality factors, and the mechanical compliance. With such values, it is possible to optimize the installation location in the vehicle and to linearize the frequency response using DSP units (Digital Sound Processors). High-end car audio systems particularly benefit from:

• RTA Analyses (Real Time Analyzer): Immediate evaluation of the frequency spectrum.
• Phase and runtime corrections: Avoidance of overlap between woofers and tweeters.
• Correction of room modes in the interior: Eliminating frequency boosts caused by hard sound surfaces.

For example, anyone who wants to upgrade their sound system in an Opel Corsa or a BMW 1 Series will achieve more accurate results in speaker selection and later fine-tuning with the help of a measurement microphone. Even in premium classes from Audi or Mercedes, small reflections and resonances are present, which can be quickly identified and eliminated with good measurement equipment. This makes the soundstage more natural and each instrument sounds more authentic.

Compatibility check and consultation by Masori

A major concern in all car audio projects, besides acoustic performance, is also compatibility with existing audio accessories such as amplifiers, DSPs, or car radios. Measurement microphones should always be tailored to the specific requirements of the respective system. Masori provides several aids for this purpose:

• Compatibility Check via AI Chatbot: Quick verification of which microphone is suitable for your vehicle and your goals.
• Online shop filter: Search specifically for features such as frequency band, impedance, and sensitivity.
• Expert support: Detailed consultation about FAQ and Help – with technical tips for installation and optimal positioning.

Since the requirements for plug-and-play retrofits in a SEAT Leon are different from those for a complete conversion of a VW T6, it is worthwhile to check the parameters of the measurement microphones before purchase. This ensures that there are no signal losses or distorted measurement curves during later measurements.

Practical results through calibration and software integration

To fully utilize measurement microphones, it is recommended to use appropriate analysis tools. Common software packages such as REW (Room EQ Wizard) or TrueRTA enable real-time evaluations and frequency analyses. For precise calibration, the following should be considered:

• Update device drivers to ensure the microphone is recognized smoothly.
• Determine the reference level in the room by playing a calibration tone through the speakers.
• Perform microphone calibration using the reference data.

Especially in speaker tests for powerful subwoofers or high-resolution tweeters in the car audio sector, regular calibration is absolutely necessary. Only in this way do the measurement values remain reproducible and allow accurate comparisons between different components.

Why professional measurement microphones are a worthwhile investment

In many cases, audible sound improvements can only be achieved through solid data. Professional measurement microphones help identify problematic frequency ranges such as 200–300 Hz or 3–5 kHz and optimize them accordingly. Upgrade enthusiasts who want to equip their Opel Astra with crisp kick bass or turn their VW Passat into a high-end soundstage achieve precise tuning by using a high-quality measurement microphone. In addition, the devices allow for seamless documentation of the tuning progress.
