Speech Blocker

This preset is specifically engineered to mask human speech frequencies (300-3000 Hz), where vocal sounds are most prominent. The mid-frequency boost creates an effective barrier against conversations, phone calls, and office chatter. Research shows that intelligible background speech is one of the most distracting sounds for cognitive work. By making speech unintelligible, this preset helps maintain focus in open offices or shared spaces. The spectrum is designed to obscure speech without being overly loud. Best for: open-plan offices, coworking spaces, studying in cafés, blocking neighbor conversations.
