Explore the complexities of achieving “good” sound in music reproduction, from speaker response to the impact of EQ. Dive into Audyse’s approach using Digital Signal Processing for a flat headset response, and discover how personal taste shapes the pursuit of perfect sound.

We’ve seen how motorcycle helmet noise arises, why your helmet doesn’t prevent it from happening, and how active versus passive noise cancellation handle different parts of the frequency spectrum more effectively. Now we’d like to talk about how active cancelling can help your ride.

In the realm of sound-blocking, ear-muff style protection offers passive defense by forming an air-tight seal. Helmets, however, lack this seal, allowing low-frequency noise to penetrate. Passive methods falter against low frequencies, whereas Active Noise Cancellation (ANC) excels, particularly below 1 kHz.

Where does it come from? How loud is it? And most importantly, what can I do about it? We all know how loud motorcycle noise is, but do you know what noise you actually hear?

In this blog series, we explore Active Noise Cancellation (ANC) and its challenges. ANC works by generating “anti-noise” to cancel incoming sound, but achieving precision is tough. With varying frequencies and changing sine waves, cancelling noise without losing desired sounds poses complexities we’ll delve into later. Stay tuned for more insights!

I think we can all agree, that when we started riding motorcycles, we didn’t expect the wind noise on the highway to be deafening, but yet, here we are…

As an experienced R&D engineer, I was accustomed to analyzing performance data without judgment. But the recent motorcycle ride testing had a different impact, especially since I had been the test rider using my own helmet and bike. The results were worse than expected, revealing extreme in-ear sound pressure levels (SPLs) that hit home, as my own ears were affected.
