Apple’s New Noise App is a Game Changer

As one of the world’s leading acoustic measurement specialists, we like to keep up-to-date with developments in the market. The new Noise app on the Apple Watch promises to change the way noise is perceived by the general public, so we took a closer look.

Our take on Apple’s latest technological innovation

You might have heard that Apple has released a handy new app in its latest update to the WatchOS platform. Wearers can now track their noise exposure throughout the day, receiving real-time alerts when their environment is too loud. As one of the world’s leading acoustic measurement specialists, we like to keep up-to-date with developments in the market. Even though we already knew this app was in the works, we still tuned in to see its announcement on 10th September – along with the millions of dedicated Apple fans from around the world.

Apple is well known for creating genuinely life-changing technology, which many people claim began with the launch of the iPod in 2001. Since then, it has driven the mobile phone market to a point where nowadays, phones are seen as an extension of our very being. As a master of expanding markets, we have no doubt Apple’s development of this app can only be a good thing. Of course, there is no substitution for scientific instrumentation like the equipment we make, which is designed to measure a massive spectrum of sound in precise detail. However, the advent of this app will drive a more comprehensive appreciation of the harm that high noise levels can have on people’s health and wellbeing. Raising awareness of this was one of our fundamental founding principles back in 1970.

So, let’s have a look, shall we? Getting hands-on with the Noise app.

Starting the app is nice and simple, in true Apple fashion. As it’s native to Apple Watches (Series 1 onwards – for those of us that have the very first generation of Watch, we’re out of luck), it works as seamlessly as long-standing wearers will have come to expect. Its interface is clear and easy-to-understand, with a helpful introduction that explains how the app works and what the different noise levels mean for your hearing

We’ve seen warnings about hearing health on smart technology before; turn the volume on your phone up when wearing headphones and you’ll notice the bars change colour. However, this new app isn’t limited to when you’re enjoying the latest tunes. As you wear your watch throughout the day, it’s always listening to the ambient noise levels, checking to make sure that your hearing is kept safe.

That’s the impressive thing about this app: it’s not one of those apps where you have to have it open to get it to work. It provides real-time alerts for when your hearing is potentially at risk, in the form of haptic feedback or a visual warning.

But a wearable noise monitor isn’t necessarily new technology. In 1995, we introduced the world’s first wireless noise dosimeter: the doseBadge. Durable, robust and light, the doseBadge is what has set the standard for wireless noise dosimeters ever since it launched. 

How do they compare? The Apple Watch vs the doseBadge

It’s difficult to estimate precisely how many doseBadges are out there in the world, but we reckon it’s definitely more than 20,000! Not quite as many as the 22.5 million Apple Watches that were shipped last year…

When comparing the two devices, there are a few key things to consider. Firstly, there’s the durability. Remember, the doseBadge survived a trip through a stone crusher and being driven over by a two-tonne pickup truck; it’s a tough little piece of kit! Over the years, smart technology has fallen foul of criticism about its ability to take a knock or two. As materials improve and build quality gets better, it’s becoming less of an issue. Although it’s still unlikely the Apple Watch could survive what the doseBadge has. Sorry folks.

The Premier doseBadge was initially released in the 90s and remains one of our most popular instruments!

Then there’s the more critical issue of legislation compliance. I know: talking about regulations isn’t the most exciting thing in the world, but it’s what all our equipment is designed for. The doseBadge meets the Control of Noise at Work regulations and industry-specific standards, which means you’re guaranteed to get more accurate noise data. As an avid Apple user myself, I can say that the quality of their kit is unrivalled by many in the industry, which probably explains the hefty price tag on everything. With that said, it’s highly unlikely that Apple products meet the same acoustic standards that our plucky little doseBadges do.

Regulations state that a noise dosimeter should be calibrated every year by a professional laboratory, and at the start and end of every measurement. It’s dead easy to calibrate one of our doseBadges; less so for the Apple Watch. The internal microphone can’t be accessed for calibration and if we know anything about microphones, it’s that their accuracy can fluctuate over time, hence the need to calibrate.

Although both pieces of tech are wearable, where they’re worn makes a difference. The doseBadge is designed to be worn on the shoulder close to the ear, so it can capture the noise levels as experienced by the wearer. With the Apple Watch on someone’s wrist, noise levels will read differently than what is actually experienced in the ear. So, your readings may not be all that accurate.

When comparing the doseBadge with the Apple Watch, there’s not much in the watch’s favour. I mean sure, it looks funky, but it just can’t compete with the doseBadge in terms of its applicability to the health and safety industry.

So, what do we think? Our thoughts on the Noise app.

Taking everything I’ve already said, I think it’s fair to say that the Apple Watch isn’t attempting to be a replacement for a noise dosimeter like the doseBadge. Of course it isn’t going to be as accurate as the “real thing”, but it’s not trying to be. And what it does successfully is so important. It raises awareness of noise and hearing health to a whole new swathe of people who have probably never considered it before. That’s huge.

I’ve spoken to several people here at Cirrus, and we’re all in agreement that this app is superb. We’ve been in the industry for almost 50 years and know how damaging noise can be. Whether it’s hearing loss or other health conditions like cardiovascular disease and depression, it can have such a negative impact on people’s lives. Trying to convince people that they need to look after their hearing isn’t as easy as convincing someone to buy an Apple Watch. But now Apple has created this app, noise and hearing health is going to be in the public’s mind far more than it ever has been, and from where I’m standing, that can only be a good thing.

Awareness surrounding hearing health is on the rise. There have been several high-profile cases in the last year that have highlighted the impact that noise can have on someone’s health. Additionally, February ’19 saw the World Health Organisation produce guidelines that outline a standard for safe listening on mobile devices. Included in these guidelines is a recommendation that users should have the ability to limit the maximum volume level when listening through their headphones, something which has been available on smartphones for a while now.

This most recent development from Apple goes hand-in-hand with what Cirrus has been doing since its inception. We exist to help organisations limit their impact on people’s hearing, health and wellbeing in easy-to-use and straightforward ways that challenge the rest of the market to change the way they do things. 

Hats off to you, Apple. When it comes to noise, you’ve clearly taken a leaf out of our book. 


Measuring personal noise exposure – noise dosimeters

When you need to measure the amount of noise a person is exposed to during the course of their working day, you need a noise dosimeter. They’re attached to the person’s clothes and follow them around their workplace for the duration of their shift, recording every noise level they’re exposed to. If needs be, the data they capture can be used to help you determine the most appropriate and effective PPE for staff to wear. How useful is that?!

We revolutionised the world of noise dosimetry. It’s true: we really did. Before we invented the doseBadge in the 90s, every noise dosimeter was full of wires, buttons and displays, not only making it potentially unsafe but also risking the integrity of the data as wearers could easily tamper with it.

The strong and robust one

The doseBadge is the ultimate tool for measuring someone’s personal noise exposure in harsh environments. It’s robust aluminium casing helps this little device withstand the toughest applications, whether it’s being driven over by a two-tonne pickup truck or put through a stone crusher – and yes, we really did do both of those things.

The doseBadge is also available with Intrinsic Safety certification, meaning it’s safe to use in places with potentially explosive atmospheres including, oil rigs, mines and areas in the petrochemical industry.

The smart and discreet one

The doseBadge Pro is the perfect noise dosimeter for those environments where discretion is key and where the ability to withstand a stone crusher is non-essential. With Bluetooth® connectivity, the doseBadge Pro can be used remotely from your smartphone, meaning you won’t have to disturb the wearer to view live data readings or to start/stop measurements.

It’s sleek discreet design means it’s perfect for measuring personal noise exposure in bars, nightclubs, theatres and in the uniformed services.
