Frank alerted me of this new post on WIRED which states that "musicians can pick out relevant speech sounds from a noisy environment better than non-musicians, suggesting that musical training helps people hear better under “speech-in-noise” conditions like a restaurant or crowded room."
How did they come to this conclusion? They did some tests, bringing in a bunch of musicians and non-musicians and making them listen to sentences in noisy conditions. The musicians greatly outperformed their less shreddy counterparts. The level of experience a musician had also mattered, as that helped along with focus and memory. Overall, its a pretty fascinating article, definitely worth checking out.
