6.4.5  Hand-held hands-free UE sendingp. 46

The sending sensitivity frequency response from the MRP to the SS audio output (digital output of the reference speech decoder of the SS) shall be as follows:
The sending sensitivity frequency response shall be within the mask which can be drawn with straight lines between the breaking points in Table 13 on a logarithmic (frequency) - linear (dB sensitivity) scale.
Frequency (Hz) Upper limit (dB) Lower limit (dB)

6 3005-10
8 0005
NOTE:
All sensitivity values are expressed in dB on an arbitrary scale.

Compliance shall be checked by the relevant test described in TS 26.132.

6.4.6  Hand-held hands-free UE receivingp. 46

The receiving sensitivity frequency response from the SS audio input (analogue or digital input of the reference speech encoder of the SS) to the free-field shall be as follows:
The receiving sensitivity frequency response shall be within the mask which can be drawn with straight lines between the breaking points in Table 14 on a logarithmic (frequency) - linear (dB sensitivity) scale.
