During vocal recordings, there is a particular noise referred to as pop noise which occurs usually when there are p or b sounds present in the word being spoken or sung, and these undesirable popping sounds will be recorded without a pop filter. It is therefore understood that a pop filter is an essential recording gear for vocal recording. In addition, using a pop filter can also prevent microphone moisture contamination caused by saliva while singing. Since a condenser microphone diaphragm is light-weighted and it may affect the sound if the diaphragm is contaminated, but this pop filter can prevent this.
