No... Noise cancellation requires electronic circuitry that "listens" to noises and attempts to send out the exact opposite sound profile, thereby cancelling out the original sound.
There are a few physical principles which limit the effectiveness of noise cancellation as an intervention method for snoring noise distractions.
- Snoring sounds fluctuate too rapidly (both in volume and tone) for noise cancellation circuitry to respond effectively. Noise cancellation is best suited to deal with consistent, predictable sounds, such as airplane noise, wind, etc.. Noise cancellation is commonly used to limit background sounds that would contaminate music clarity and enjoyment.
- Noise cancelling headphones ONLY have any effect at all on the sound that would otherwise have entered directly into your ear canal. They CANNOT do anything about the sound that vibrates your skull and travels through your head, to your inner ear. So about 50% of the original volume of the snoring reaches your inner ear without ever being altered by the noise cancellation circuitry. In other words... enough snoring noise volume simply bypasses the noise cancelling device and you wind up being distracted anyway.
- Aside from the facts described above, there is no noise cancellation technology in existence that is capable of 100% cancellation. The best that can be achieved is partial cancellation, which means that you would still be disturbed by the fluctuations of intermittent snoring sounds, even if bone conduction was not such a significant factor
