Education: Intelligent Audio & Its Benefits For Noisy Environments

Eemits Requalifies for SafeContractor Accreditation

Noisy environments can be counterproductive in regard to staff and students having open dialogue. Clear conversation is important for student development – and it shouldn’t be hampered by background noise that causes distress or disruption. 

But you want and need a thriving environment, so background noise is not something you can easily stamp out. 

In our last Education Pain Points series blog, we focus on Intelligent Audio and how it will combat both noisy environments and quiet ones so your facility can be efficient as possible. 

Intelligent Audio

Intelligent Audio is a smart feature on certain radio devices that uses intelligence to decide when out increase or decrease radio volume, depending on the type of environment you’re in.   

Noisy environments

In noisy environments, radio volume will automatically be increased. This is good in full classrooms, busy corridors, and canteens – should there be an instant need to communicate. 

Quiet environments

If students are sitting exams, but nearby staff have their volume set to high, the feature will monitor this and automatically reduce volume levels. 

This will allow staff to hear what’s being said and students won’t be disturbed from the task at hand. 

Noise cancellation

Noise cancellation helps to improve speech transmission. Using the radio’s built-in microphone, advanced audio processing technology is used to automatically reduce background noise. 

No need to raise your voice

Educational facilities are high-pressure environments, and staff can raise their voice to make sure they’re – especially if students are talking at once. 

But, with Automatic Gain Control (AGC), this isn’t a problem. AGC will automatically adjust the microphone level on the radio being used for transmission, so louder sounds are kept at a reasonable level. 

Feedback suppression

When two or more radio users are too close together, and one of them speaks via their two-way radio, their voice will cause interference.  

This comes in the form of looping and howling noises. To prevent this happening, acoustic feedback suppression can be enabled to ensure things can carry on as normal. 

A detention for decibels

High noise levels and noise pollution. Just reading those words together is enough to make your ears hurt. And for educational settings, noise levels can be hard to control. 

Plus, you also have scenarios where you need to ensure no noise is produced at all. To put things into perspective, let’s take a look at the statistics that back up the notion that you should always take background noise into account. 

WHO says what?

In a classroom environment, the World Health Organisation (WHO) recommends 35 decibels as the limit for background noise. Any noise that exceeds this limit will make it more difficult to communicate and distinguish speech. 

For context, 35 decibels are somewhere between being in a quiet rural area and a bird singing. Given that students can be more boisterous than a sparrow or a pigeon, having Intelligent Audio in place will make it far easier to get your message across when the time calls for it. 

A pollution puzzle 

Staying on the topic of noisy environments, one research paper found that the average classroom noise level reached 72 decibels – nearly the volume of a vacuum cleaner – meaning that staff and students have a hard time hearing each other. 

In fact, the same paper found that teachers were talking with a raised voice 61% of the time, which not only increased noise level, but also provided evidence for a link between noise exposure and cognitive fatigue. 

Busy universities, whether it’s studying or partying, can also create high levels of noise pollution. So, if you’re maintenance and security staff need to be heard loud and clear, then Intelligent Audio could be the perfect solution for them. 

Quiet please – exam in progress

The most high-pressure situations in schools, colleges, and universities are often exams. They require high levels of concentration and focus, and low levels of noise. 

Any type of distraction can have a negative impact on a student’s score or grade. There’s been several studies that suggest background noise can hamper concentration levels when studying for an exam, with the same notion true for the exam itself. 

Student chat forums are littered with topics about experiencing noise in exams – and how it distracting and stressful it can be. 

If your staff have their radio volume too high and forget to turn it down, it could be detrimental to your students’ success. 

Intelligent Audio will automatically monitor your environment, and if things are quiet for a reason, it will adjust your volume, so distractions are kept to a minimum.
