*The science behind shankhnaad , clapping and other sounds*
Human ears are capable of hearing sound waves from 20 Hz to 20,000 Hz ( or 20 kilo Hertz) which is called as the audible range , sound waves above 20 kilo Hertz are inaudible to human ears and are called as ultrasonic sound waves ,
These ultrasound waves have unique anti-microbial sterilization properties which can destroy most of the harmful bacteria and viruses within 10-15 meter radius in air
*blowing a conch (shankh) generates high amount of ultrasound (above 20khz) along with audible sound which creates a sanitized and sterile zone within a 10-15 meter radius in surrounding air* and walls are not a barrier for ultrasound waves ..clapping, ringing bells and drumming utensils may generate similar ultrasound with smaller sterilized radei..
(for further details you can google ultrasonic sterilization)
