Everyone hears differently. So then, why does every other earbud manufacturer create products that are essentially the same? What if there was a technology that uses highly sensitive microphones to distinguish your hearing differences and then tunes the sound to match the way you hear?
Introducing Masimo Adaptive Acoustic Technology (AAT).
Masimo AAT is the culmination of a 30-year exploration in signal processing and centers around the measurement of Otoacoustic Emissions. These are sonic reflections that originate inside your ear from the cochlea. The loudness of an OAE at a given frequency depends on the sensitivity of each ear at that frequency. By measuring OAEs, we can determine which frequencies your ears are more or less sensitive to. Once the hearing measurements are complete, they are processed to create your unique hearing profile. The goal of Masimo AAT is to address the hearing needs of the many—without creating custom, cost-prohibitive earbuds for the few. Integrating this technology with Denon's audio engineering prowess has created incredible products - the Denon PerL and Denon PerL Pro.
Unlike other premium headphones and earbuds, the Denon PerL and Denon PerL Pro use Masimo AAT to make every instrument sound even more distinct and present—you’ll feel like you’re in the audience, enjoying a live performance. And when you’re at the gym, the sound quality of your favorite workout playlist will be more vivid and easier to listen to. Then, when you’re on the bus for the last leg of your evening commute, you won’t miss a single word of the audiobook you’ve been devouring. By measuring each person’s hearing sensitivity and tailoring the sound to suit, Masimo AAT ensures no musical detail is left unheard.
Masimo AAT marks a technological milestone in the pursuit of fantastic sound. And for those who are obsessed with sound, personalized listening just mean one thing—you’ll experience music like never before.
