6.4.5 Hand-held hands-free UE sending p. 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) |
|---|---|---|
| 100 | 0 | |
| 200 | 5 | -5 |
| 5 000 | 5 | -5 |
| 6 300 | 5 | -10 |
| 8 000 | 5 | |
|
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 receiving p. 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.
| Frequency (Hz) | Upper limit (dB) | Lower limit (dB) |
|---|---|---|

| 630 | 6 | -12 |
| 800 | 6 | -6 |
| 4 000 | 6 | -6 |
| 6 300 | 6 | -12 |
| 8 000 | 6 | |

NOTE:
All sensitivity values are expressed in dB on an arbitrary scale.

It is recommended as a performance requirement that the receiving sensitivity frequency response be within the mask which can be drawn with straight lines between the breaking points in Table 14a on a logarithmic (frequency) - linear (dB sensitivity) scale.
| Frequency (Hz) | Upper limit (dB) | Lower limit (dB) |
|---|---|---|
| 315 | 6 | |
| 400 | 6 | -12 |
| 500 | 6 | -6 |
