do dogs hear twice as loud as humans?

Dogs hearing is certainly more sensitive that human hearing with all breeds having different levels of sensitivity. Loud music can damage human hearing at a certain level so it can also easily damage a dog's hearing.

I would recommend to put in headphones so that you are only damaging your own hearing.

She's probably hearing the volume at a slightly louder level than you, but dogs' hearing exceeds humans in the frequency range at which they hear. Meaning a dog can detect sounds far beyond the upper limits of the human auditory spectrum. They are also better at pinpointing the location of the sound.

But as humans can damage their ears listening to too loud sounds, so too can a dog suffer hearing impairment.

Dogs can hear a lot better than humans.

She is hearing about 100 times what you hear.

yes, dogs are more sensitive to sound than humans.

some sounds that we tolerate are painful to them.

Naw lol that's fake. But they smell is better. Fart in their face and laugh at them when they inhale ur stank! Haha then abandon the dog and get a hippo

" is it screwing up her hearing" Yes, and your's also.
