All You Need to Know About Personalised Sound with Denon

Listening is personal. Our physical body, the world around us, subjective preferences, and experiences affect how and what we hear. At Denon, we’re fascinated by the potential to transform the way we hear sound into a truly personalised experience and that’s exactly what we’re doing. Recognizing that there’s a spectrum of audio uniquely perceived by everyone, our Denon PerL and PerL Pro earbuds are tuned to the sensitivities of each individual, creating a more profound, rich, and fulfilling experience.

In this guide, we’ll introduce you to the idea of personalised sound: what it is, how it works, what personal sound headphones do, and why they can utterly change the way you listen to the sounds of music, films, games, and the world around you.

What is personalised sound?

Sound might seem objective, but that’s really only the case for machines. In reality, we each perceive sound differently, and that’s affected by our physiology, personal experiences, and age. This is the basis of personalised sound: if we can adjust audio to suit individuals, we can tailor a listening experience with greater clarity than most have ever heard.

You can think of personalised sound as a much more rigorous equalizer (EQ). An EQ tuning adjusts the relative volume of the sounds we can perceive—from 20Hz to 20kHz—by focusing on particular frequencies. You might have used a graphic EQ on a stereo to adjust the sound to suit your taste or the environment, bumping up the bass or shaving off some high-end. Personalised sound works similarly but with much greater accuracy and control. We’ll go into the specifics of how Denon personalised sound works below, but at a basic level: our products tweak the sound in response to your hearing feedback, producing audio best suited to you.

How does personalised sound work?

Our process isn’t based on subjective feedback; it’s driven by Masimo Adaptive Acoustic Technology (AAT). To truly map the sensitivity and unique qualities of your hearing, there’s a simple and objective test: when sounds are played into the inner ear, the cochlea responds by producing small sounds in return. This audio phenomenon (called otoacoustic emissions or OAE) is louder across frequencies to which you’re more sensitive, and the data produced from these tests then determine how best to shape audio to give you the best experience.

To get this information, we use some self-contained, self-learning technology. Our earbuds contain tiny microphones that perceive the volume of OAE in your ear, identifying how sensitive your hearing is to specific frequencies. Using this data, Masimo AAT adjusts frequencies across the acoustic spectrum so that what you hear is much closer to how the audio is supposed to sound. The audio will be uncolored by the idiosyncrasies of your own ear, giving you the most faithful audio representation possible.

Personalised sound applications in different industries

Personalised sound depends on the individual, but here are a few potential applications:


Immersive sound is part of the gaming experience, helping us leave our lounge room and enter the game world. Games are often sonically dense, but personalised sound can give clarity to the music, audio effects, and dialogue so that everything is perfectly balanced and crystal clear.


People often consider live music to be the most incredible musical experience because everything is so clear and present. Personalised sound can give audio recordings the same presence and vitality as live music, giving space and precision to individual instruments.

Health and Wellness

Consider therapeutic soundscapes for sleep or anxiety, with every frequency perfectly tuned so as not to distract. The ideal background music or relaxation soundtrack needs to be comfortable and subtle while still being clear—this is the advantage of personalised sound.

Film and entertainment

Like gaming, film and television are transportive. The sort of realism personalised sound provides is vital in making a good film great, and this is of particular advantage outside of the expensive sound systems of the cinema.

Advancements and the future of personalised sound

We’re just scratching the surface of what personalised sound can be. With continual advancements in this exciting technology, the future of audio is clearer than ever. Here are a few things to look out for in the coming years:

Increased personalisation

Our personalised audio offers precision and clarity of sound that we expect will only keep improving in the future. We’re excited about future technological advancements that will provide an even greater level of individualized audio based on preferences and the hearing profiles of our users.

Integration with smart devices

Personalised sound has so much potential beyond earbuds and headphones. With the broader adoption of smart devices throughout the home and beyond, audio personalisation may start filtering into almost every aspect of audio playback.

Advanced technology

It’s reasonable to expect that, as Masimo AAT gains wider acceptance, personalised sound will become more accessible and available. This could include advances in affordability that would benefit the general public.
