M32 MARK3

MARK3 MilPro is a new model of headset that can protect hearing and improvesituational awareness and communication in noisy environments. With moreadvanced functions and levels, it can be adapted to different scenarios forenvironmental listening. In addition, a replaceable bracket is designed to beinstalled on the helmet rail for the convenience of users.M32 Mark3 has anadjustable angle microphone and a Nexus TP120 Kevlar communication wire, itcan be connected to communication equipment through the EARMOR M51/ 52 PTT(or NATO standard military-standard PTT) to complete the function of transmittinginformation. M31 Mark3 comes with 3.5mm AUX audio input cable for mediadevices. 

 

 

5 Task modes can be switched

Press the volume “+” and “-”buttons to switch between fivemission scene modes:

 

1.Quiet ModeIn a high-noise environment,it can automatically shieldoutside sounds and use radioto communicate

 

2.Comfort modeSuitable for in-car or indoornoisy environment, longrelease time to prevent echodamage

 

3.ConversationRestore the real environmental sound,completely simulate the normal hearingof human

 

4.Patrol modeAmplify the ambient sound appropriatelyto more clearly perceive the surroundingenvironmental sound

 

 

5.Observing modeMaximum amplification of thesurrounding environment sound toenhance hearing acuity and make iteasier to hear subtle sounds

 

Modular design

The fast-switchable headset holder is easy to operate without special tools. It canswitch between different suspension systems such as headband, helmet holder,and neck holder according to different tasks.

 

 

Super Fast Attack Time

When wearing headsets, you can feelthe fast attack wave (such as whenthe gun is firing). The super fastattack time is less than 1 ms, whichcan instantly suppress the ambientsound and protect the user's hearingfrom damage.

 

External Communications& Detachable Mic

 

The M32 MARK3 can be easily connectedto the PTT of the TP-120 through themilitary-standard 4-pin U174 plug andthen communicate with the radio. Thedetachable microphone design allowsboth left and right-handed people touse it, and the windproof design allowsusers to maintain communication inwindy environments. The microphonepositioning slot can adjust themicrophone to the best use position frommultiple angles.

 

 

 

EMI/RFI Shielding & Clear voice tracking

The M32 MK III has a built-in EMI filtering system that can effectively suppresselectromagnetic waves generated by other devices in the environment, ensuringthat the headset can operate normally under any circumstances.Clear voice tracking technology improves the recognition of the voice in theenvironment, which can optimize the vocal dialogue in the environment and makethe voice clearer.

360° Situational Awareness

 

Environmental awareness is particularlyimportant for hazardous jobs such aspilots, soldiers, and police. High-Fidelityfull degree Situational Awareness (HFSA)technology provides 360° situationalawareness provided by two microphonesprovides front and back audio detection,enhancing heightened awareness ofambient environment, helps recognizingand dealing with unsafe conditions beforethey become an issue.

M32 MOD4 is an electronic pickup noise-cancelling headphone withcommunication function designed for special tasks. Can enhance weak ambientsound sources, track human voice and restore and optimize, while suppressingdangerous noises (such as explosions and gun sounds) higher than 82 dB, It not onlyprotects hearing, but also improves the clarity of conversation and the surroundingenvironment alertness. Internal EMI filtering system can effectively filter theelectromagnetic interference generated by other electronic equipment. With anadjustable angle microphone and a Nexus TP120 Kevlar communication wire, itcan be connected to communication equipment through the EARMOR M51 / 52 PTT(or NATO standard military-standard PTT) to complete the function of transmittinginformation

GHearing protection is designed to reduce the harm caused by harmful noise orother treble.Improper use or improper wearing can cause hearing damage in strong noise.In order to use hearing protection headphones properly, you can consult aprofessional and read the instructions carefully or call our company for moredetails. Please do not wear headphones if the ear is ill, or improper protectionwill cause permanent hearing loss.

 

 

 

SNR means signal-to-noise ratio, also known as signal-to-noise ratio.

signal-to-noise ratio

The English name of signal-to-noise ratio is SNR or S/N (SIGNAL-NOISE RATIO), also known as signal-to-noise ratio. It refers to the ratio of signal to noise in an electronic device or electronic system. The signal here refers to the electronic signal from outside the device that needs to be processed by this device. The noise refers to the irregular additional signal (or information) that does not exist in the original signal generated after passing through the device, and this kind of The signal does not change as the original signal changes.

The higher the noise reduction value, the better the anti-noise effect.
Currently, there are two international standards for noise reduction values of sound-isolating earplugs: SNR and NRR.
Among them, SNR is a single value noise reduction value tested in accordance with the international standard ISO 4969-2;

NRR is a single value noise reduction value tested in accordance with the American standard ANSI S3.19-1974.

In comparison, the SNR of the same type of earplugs will be about 3 decibels higher than the NRR.

So In the specification file
3.1.6.1 Headphones with an electric sound input circuit must meet the
requirements of DSTU EN 352-1 (or, accordingly, DSTU EN 352-3). Estimated
average protection SNR is not less than 26 dB.

 

SNR is Simplified Noise Level Reduction (Simplified Noise Level Reduction), which is the EU standard for testing the noise reduction performance of hearing protection products.
It is a standard for evaluating the anti-noise performance of hearing protection products by testing the degree of attenuation of HML tri-frequency noise by the protection products.

NRR (Noise Reduction Rating) is a standard promulgated by the U.S. Environmental Protection Agency (EPA) in 1979 to measure the anti-noise performance of hearing protection products.
The NRR of anti-noise products currently on the market is roughly in the range of 0-40dB.

The formulas of SNR and NRR have certain similarities, but there are also certain differences.
In the SNR calculation formula, the ratio of signal intensity and noise intensity is used to represent the signal-to-noise ratio. The larger the value, the stronger the signal and the lower the noise;

Noise Reduction Index (NRR) is an index used to measure the noise reduction ability of hearing protection devices such as headphones. Generally speaking, the higher the NRR value, the better. This is because NRR reflects the earphone’s ability to attenuate sound at specific frequencies. The higher the value, the better the hearing protection provided by the earphone. Under the American standard ANSI S3.19-1974, NRR is determined by measuring the noise reduction effect at different noise levels. Therefore, when choosing headphones or other hearing protection equipment, you should give priority to models with higher NRR values.

It should be noted that although NRR is an important consideration, it should not be used as the only criterion for purchasing headphones or evaluating their noise reduction effect. Users should also consider the headset's design, comfort, and suitability for their hearing needs and personal preferences. In addition, due to the existence of different international standards and test methods, SNR (Single Value Noise Reduction) may be higher than NRR in some cases, but both are important references when comparing the performance of different noise reduction devices.
