NTi Audio Noise Sources

Noise Sources for measuring Room & Building Acoustics

The DS3 Dodecahedron Speaker Set offers a lightweight, yet powerful signal source for building acoustic measurements. The optimized frequency response ensures precise measurements in accordance with the ISO 16283 and the ISO 3382 standards. The set includes the robust omnidirectional DS3 Dodecahedron Speaker and the remote-controlled PA3 Power Amplifier.

The remote-controlled TM3 Tapping Machine is a precision impact noise source for building acoustic measurements. It is typically used for the assessment of general impacts in dwellings that occur on floors or stairs in a building, and can be operated autonomously, due to the built-in battery.
