So effectively the Gardiner frog does hear with its mouth. Frogs do not hear with their eyes. The tympanum of the frog is found close to their eyes but is not involved in the eye anatomy. Frog eyes and ears are not connected to each other. However, a frog will use both sight and sound to assess its environment. The two senses together help the frog to find prey, mates, and avoid danger. Frogs do have good hearing with situations they need to help their species survive.
Frogs will generally hear and communicate at sound below 12 kilohertz kHz. Studies have found that this frog species can hear at frequencies up to 38 kHz. Although frogs have good hearing it is very specific to what they need to hear to survive.
Situations such as hearing mating calls, detecting prey, and avoiding predators. Frogs have actually been known to adapt their behavior around environmental human noises. For example, frogs will reduce their mating calls around areas of high road traffic. Fogs use their tympanum to detect sound vibration underwater. Together with the eastucuan tube they can equalize the water pressure and detect the direction of sounds. Frogs have ears, but not the way that mammals do.
They use a tympanic membrane as an external eardrum to transmit and process vibrations. This helps to drown out sounds or to hear specific frequencies. All Frog species have adapted their hearing system well to hone in on survival tactics and adapting to their environment.
Panamanian golden frogs have no external or middle ears but are able to hear and locate sounds with their inner ears. Their lungs are located close to the skin and function as eardrums. These frogs' lungs pick up sound wave vibrations are and convey them to the inner ears, which function as other species' do and send impulses to their brains for interpretation. Gardiner's Seychelle frogs, one of the world's tiniest frogs, resonate sounds through their cavernous mouths, instead of eardrums.
They also have no external or middle ears, and have functional inner ears. X-ray imaging has revealed that small bones conduct sound wave vibrations from Gardiner's frogs' mouths to their inner ears.
