1.1 Test Objectives
The objective of this document is to define the Audio test plan for Verizon
Wireless handsets. This plan details each specific test and the specific
conditions necessary to meet Verizons test standard. The test plan will measure
frequency response and audio output under certain conditions and will confirm
the integrity of the audio path in the device. The test plan also evaluates the
device for safe audio levels to ensure no damage will be done to the customers
ear.
This document will be used by employees of Verizon Wireless and its vendors to
guide the execution of the Audio test plan.
Specifically, this document includes:
Current Audio tests performed on all voice capable devices
1.2 Definitions

All vendors must successfully follow and pass this test plan to comply with the
Verizon Wireless validation and evaluation process. Such testing will be
completed in the Verizon Wireless CPE lab in Bedminster, NJ. Entrance criteria
for applicable devices should follow all current VZW submittal procedures. Refer
to the Verizon Wireless documents "Verizon Wireless Device Testing Process"
and "Verizon Wireless Device Compliance Test Entrance Criteria" for specific
test process and test entrance criteria details

2 2.1.1 FREQUENCY RESPONSE IN SEND DIRECTION
VZ_TC_AUDIODEV_2653
A measure of acoustic sensitivity (output/input) as a function of frequency in transmit (sending) direction.
Traceability
Please see "Reqs Audio.doc" for Verizons Audio requirements
Standard HATS positions - IEEE Std 269-2002
Frequency Response measurement- 3GPP2 C.S0056-0 V1.0
Applicability
This test applies to all voice capable devices.
Pre-Conditions (Step 1)
Procedures (Step 1)
1. Place device on a call and set ear piece volume to nominal
2. Place device in standard HATS position specified by VZW (See test configuration 1.4.1) and set the position force to 6N
3. Execute test case "Sending Characteristic" in B&K software
4. The excitation level shall be -4.7dBPa
Expected Results (Step 1)
The send frequency response should meet the Mandatory Limits defined in section 2.2 of 3GPP2 C.S0056-0 v1.0. Optionally, for
the best customer experience the frequency response should meet the Desired Limits

3 2.1.2 LOUDNESS RATING IN SEND DIRECTION VZ_TC_AUDIODEV_2654
A measure of transmit (send) audio sensitivity.
Traceability
Please see "Reqs Audio.doc" for Verizons Audio requirements
Standard HATS positions - IEEE Std 269-2002
Frequency Response measurement- 3GPP2 C.S0056-0 V1.0
Applicability
This test applies to all voice capable devices
Pre-Conditions (Step 1)
Procedures (Step 1)
1. Place device on a call and set ear piece volume to nominal
2. Place device in standard HATS position specified by VZW (See test configuration 1.4.1) and set the position force to 6N
3. Execute test case "Sending Characteristic" and "SLR" in B&K software (Note: SLR is calculated from data obtained in "Sending
Characteristic" test.)
4. The excitation level shall be -4.7dBPa
Expected Results (Step 1)
The Send Loudness Rating (SLR) shall be 11 dB +/- 5 dB.
