eli5: Why are your ears more sensitive at night?

482 views

Why do louder volumes hurt your ears less during the day than they do at night? For example I can have my headphone volume at about 7/10 and my ears feel comfortable, however the same volume at night not only sounds louder but makes it uncomfortable to listen to, so I have to turn it to 3/10 which makes it more comfortable.

Your ears work by detecting sound that is louder than background noise. The ear senses differences in volume, not the true measure of loudness.

So what loud is determined by its relative energy to sounds around you.

At night, there is usually less going on and therefore it is literally quieter. So 7/10 now sounds really loud compared to the quiet night, and 3/10 seems the same as 7/10 during the day.
