i have yet to find the answer on this forum. anyone know ? :P doesent look like she's got ears

I've wondered this, too. I don't think they can by the way they act and react to noise (I never see any reaction.) Honestly, I have no idea, though.

Chameleons have no outer ear opening but their inner ear is just as developed as other lizards. This means that their ability to detect airborne sound waves is limited to frequencies that are able to transmit into the inner ear through the skin and tissue. These frequencies tend to be more low pitched sounds of longer wave lengths. They convert into vibrations better then high pitched/short sound waves, which can then be transmitted to the inner ear. This is why substrate vibrations in the environment are well detected by chameleons and why they produce and utilize them for communication.

I don’t think they can hear. I think it’s a good thing because I can vacuum or listen to music loud with out feeling like im scaring them lol

Vacuuming and playing loud music both fall into the category of low frequency sounds that chameleons can hear and will respond to. In high amounts, it can be very stressful to them.

For those of you who like a lot of base and loud music.....YOUR STRESSING YOUR CHAM.....and us old folks. The vibrations are annoying .

Here is a thread about their hearing...
Do Chameleons Hear?

I wonder if the inner ear is what causes the babies in the wild to all hatch out around the same time.

Can the hear me yell at my kids to "Quite Down! The Chameleon's Sleeping!!!" ??

Low frequency noises can come from pretty much everything in your house, the phone ringing, TV on, you talking, listening to music. There is no such thing has a free low frequency room. Now in High quantities yes maybe it is stressful but you don’t know 100% I would say it would be more stressful having your chameleon walk on top of a cowboys hat on your head. Yes I do vacuum once a week and keep my place clean. I don’t blast my music or bass to where my neighbors are pounding on the wall or have my speaker’s right next to the cage. I didn’t mean to sound like a horrible pet owner when I said I can vacuum and listen to music loud with out them hearing adding “what my cat and dog would hear
