Preliminary Study

A preliminary study to investigate whether or not long-term exposure to very low frequency sound at a moderate intensity below 100 dB(SPL) affects the vestibular function and/or motor coordination in guinea pigs was carried out. At first, optimal conditions of Rota-Rod Treadmill performance for guinea pigs were determined. Then, 20 and 40 Hz-low frequency sound at 80–90 dB(SPL) exposure was used for 150 minutes and measurement of the endurance time on the Rota-Rod Treadmill was carried out at rotation speeds of 8 rpm or 10 rpm. At 10 rpm rotation speed, and 20 Hz, 90 dB(SPL) stimulus, the endurance time was significantly reduced at 150 minutes, compared with that of the control, whereas no significant reduction in endurance time was obtained at 85 dB(SPL).
