White-noise devices improve speech privacy in office environments by masking undesirable or distracting sounds. In settings where the privacy of conversations in adjacent offices or reception areas is important, a small white-noise source—such as the sound of static or rushing air—can be placed in the room to obscure the clarity of speech from nearby areas.1

This technique effectively masks conversation sounds without being offensive or dangerous to the hearing of those working nearby. Consequently, this method is frequently employed in the offices of doctors and other professionals to ensure confidentiality and reduce the impact of distracting background noise.1
