Abstract
This study aimed to determine the pattern of intensity vector distribution of the midrange loudspeaker at frequency 3000 Hz and 6000 Hz. The 3000 Hz was selected because human ear was very sensitive to this frequency, whereas the frequency 6000 Hz was selected as an output limit of the midrange loudspeaker. The data were collected by using two condenser microphone that was connected by using a Spectra Plus 5.0 program to the computer. The data (voice) were taken at a distance of 1 meter from the center of the loudspeaker. The distance between the sample points was 10° for one position and there were 36 points for each frequency. At each sample point on a position, a second condenser microphones rotated by 36 points around the first condenser microphone. The second condenser microphones rotation interval was 10. At frequency 3000 Hz, the pattern of sound intensity vector distribution tended to spread over the front and the left side of loudspeaker. While at frequency 6000 Hz, the pattern of sound intensity vector distribution focused to the front of loudspeaker.
