In what way do you suspect they will effect your hearing gradually? Isn't the whole point that the waveform that reaches your ear is mostly destructively interfered with and is no longer physically present? Maybe there are some very high or very low frequency harmonics but I can't imagine that damaging your hearing. Maybe I am wrong!
