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.
At peak functioning, human ears can hear sounds at frequencies up to 20 kilohertz. Depending on size, breed, and age, the high end of a dogâs hearing ranges from 40 up to 60 kilohertz. The sound of the typical ultrasonic dog whistle varies between 23 and 54 kilohertz. Dog whistles work in the same ways that any other modes of training do, and for the same reasons; to wit, dogs are consistently trained to respond in a certain fashion to their use.
