Acoustic Perception (AP) is a crucial component of human sound study. The AP plays an important role in human performance in a variety of situations. The ability to accurately perceive acoustic sources (AP) provides advantages in human tasks. Noise pollution is a problem for humans that is getting worse to the point where it is threatening their ability to comprehend things clearly. With the help of a loud speaker arrangement, an attempt was made to demonstrate AP on the median plane by a human. The setup included ten individually tagged Wireless Speakers (WS) placed in front of the subject with identical distances between them, ranging from +60° to-60° above and below the subject’s ear level. Experiments were carried out on a total of 30 people, and they were all observed using a computer. Two sets of AP experiments were devised and executed for low frequency of 1500 Hz and high frequencyof 17 kHz. Without noise and with noise, the perception rates (PR) at low frequency were 5.250 and 4.550, respectively. The PR was 3.850 without noise and 3.100 with noise, according to the high frequency. The addition of noise changed the AP in the median plane, which might be used for target recognition and localization in a variety of applications.
