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!
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.
