Elevate your hearing aid verification with the Inventis Drum Hearing Instrument Test Box – a compact, high-performance solution designed for accurate evaluation of air-conduction devices in professional settings.

Execute both IEC 60118-7 and ANSI S3.22 standard test sequences for comprehensive performance analysis, including frequency response, harmonic distortion, and equivalent input noise, all within an egg-shaped wooden chamber that delivers exceptional ambient noise attenuation and minimal internal reflections.

Positioned with a floating setup via sound-transparent foam base, the Drum ensures optimal speaker-to-device alignment for reliable, artifact-free results. Ultra-compact and user-friendly, it’s the essential tool for audiologists, clinics, and manufacturers seeking gold-standard compliance without complexity.

Achieve confident fittings and quality assurance—the Drum sets the standard for HIT precision. Ready to integrate it into your workflow? Contact us today for details!
