On the Impact of Bell Sound on Ambient Particulates

Abstract

Here the authors examine whether bell sounds can have an impact onambient aerosol levels and size distribution under atmospheric conditions.The authors present calculation results for acoustic coagulation by churchbell sounds for a range of ambient aerosol types. The results show thatfor orthokinetic sonic agglomeration, while the frequency spectrum ofchurch bells is ideal for causing coagulation of ambient aerosols, the soundpressure level (SPL) becomes too low for an effect. However, for verypolluted conditions, at extremely short distances from the bell dust aerosolscan readily undergo sonic coagulation.
