This study is to develop a procedure of measuring the influences of the head shadow effect and pinna effect by stimulus intensities and stimulus frequencies (125 Hz to 8 kHz) based on the stimulus source at azimuth angles (0 degrees -180 degrees ). In this study, the head shadow effect would be affected by the stimulus frequencies at 3-8 kHz, and the difference of sound pressure for bilateral ears was 7.46-41.40 dB SPL. The pinna effect would be affected by the stimulus frequencies at 3-8 kHz. The difference of sound pressure for all sound sources was 6.62-35.69 dB SPL. The pinna effect would occur most apparently at 135 degrees of azimuth. Consequently, the sound intensity would not affect the head shadow effect and the pinna effect. On the contrary, the pinna effect, the head shadow effect, the frequency of stimuli and the sound location should be considered for hearing aids selection for hearing-impaired listeners. |
