The studies are part of a new trend: to look for integration of response rather than investigating each part/function separately. The fMRI studies show that touch has a wide impact on the brain, influencing our sensations, our movements, our thought processes and our capacity to learn new movements.
Dogs are most sensitive to sounds in the frequency range from 500 to 16kHz. REVERBERATION TIME. This is the time for a sound to decay to 60dB. Kennels by their nature have poor acoustic properties; hard, smooth surfaces do not absorb noise, therefore any noise generated tends to reverberate inside the building.
So, dogs can hear sounds that human cannot, for example: bats: they use ecolocalization yelling sounds from 14 kHz to 100 kHz, so dogs hear them better than humans do. rats: they chat at ranges from 20 kHz to 50 kHz, so ratter dogs can perfectly hear them. frogs: they chat at 35 kHz, so dogs hear them too
