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.
It can also function as a dog training device by pressing the power button in conjunction with the verbal or hand command. The Ultrasonic Dog Chaser. The ultrasonic dog repeller emits a frequency ranged from 20,000 Hz to 25,000 Hz intervally which is hardly audible by humans but can be heard by dogs or cats. The dog chaser may harmlessly deter the approach of a dog or cat when properly used.
