HMS II.3-LN (Code 1230.3)
Head Measurement System with Low-Noise Ear Simulator and Mouth Simulator

HMS II.3-LN contains a low-noise ear simulator based on IEC 60318-4. Besides all measurement scenarios covered by HMS II.3 (handheld / handsfree telephony), it is ideally suited for high precision acoustic measurements of headsets, headphones, earphones and in-ears with and without active noise cancellation.
Its exceptionally low intrinsic noise level of 16 dBSPL(A) allows measurements at very low SPL levels. Combined with an upper SPL limit of 148 dBSPL, HMS II.3-LN sets a new standard unrivaled by other artificial heads in the field.
Anatomically shaped pinnae (type 3.3) enable conclusive measurements of in- / on- / over-ear devices. By replicating the human anatomy according to ITU-T P.58, HMS II.3-LN also supports arbitrary free-field measurement scenarios. The ITU-T P.58-compliant artificial mouth of HMS II.3-LN reproduces the complete spectrum of human voice with a low-distortion two-way design, allowing high-quality super-wideband and fullband measurements.
