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.
This is because the sound waves are muffled by the floppy ear; still dogs hear a much higher and lower frequency than what we humans can. A dog has a hearing frequency of about 40 Hz to 60,000 Hz. The human hearing frequency is pegged at 20 Hz to 20,000Hz. However, dogs are known to be very sensitive to loud sounds. Loud noises that can be tolerated by humans would be extremely painful to dogs.
