Amerizon - Managing Background Noise With Two-Way Radio Communication

Minimizing background noise during business critical communications is a necessity for many workplaces, including the construction and manufacturing fields. Workers in the field need to be able to clearly hear each other despite the nearby sounds of heavy machinery operating. Fortunately, two-way radios are communication devices that automatically diminish this distracting and irritating background noise. These durable devices are capable of reducing noise levels because they have one, or a combination of the following features.

Intelligent Audio

Two-way radios with the Intelligent Audio feature monitor levels of background noise and adjust the speaker volume accordingly. This feature enhances the audibility of calls using the radio’s microphone. How exactly does it work? When the microphone detects a loud environment, the speaker volume is automatically increased. This function gets rid of the need for radio users to manually adjust their own volume controls.

IMPRES Audio Accessories

These accessories work to optimize audio processing even further. IMPRES Audio accessories communicate their own unique set of audio parameters to a radio’s digital signal processor, the DSP, which fine tunes the audio signal from the microphone. This feature adjusts the gain automatically to compensate for different input levels. It is ideal for radio users who, for example, while operating machinery can’t speak directly into the microphone.


Windporting functionality minimizes the overwhelming howling sounds that are commonly heard when communicating via a device in a windy environment. This technology is especially helpful in severe weather, if you use a lapel or a remote speaker microphone. It’s also very useful in rainy conditions, as it prevents water from clogging the microphone.


Acoustic Feedback Suppressor

If you’ve ever accidentally made a group call when standing nearby a coworker who has his own radio on hand, then you’re probably familiar with the annoying feedback that is often heard in such scenarios. The acoustic feedback suppressor blocks feedback from other radios, so you never have to move if you have a colleague nearby. Using an advanced software algorithm, radios with this feature recognize and discard feedback instantly.

Automatic Gain Control

This feature ensures that regardless of whether the speaker shouts or whispers into the microphone, the audio that is heard on the receiving end will come out clear and of the best quality. More specifically, it produces uniform voice volume levels on the receiving radio. It’s most convenient when you have some users whose microphones don’t face their mouths and others who do.

User-selectable Audio Profiles

Because different people have different hearing and volume preferences, many radios come with the ability to set your own audio profiles. This is also beneficial if you use your radio in multiple locations with various noise levels, because you can have one profile with different volume settings for each location.

SINC+ Noise Cancellation

SINC+ applies exceptional, lasting background suppression for those users who are consistently in extremely noisy environments. This feature also works to provide the highest quality of speech detail for those who move between noisy and quiet locations, by altering the amount of suppression based on the volume of background noise detected.

Depending on your specific work environment and conditions, each of these features would be an effective solution to minimizing background noise. Any one of these features can be found on a Motorola two-way radio. Some Motorola radios have a combination of multiple audio features as well.
