Descriptions of the audio templates provided by the Motorola are as follows:
• General Purpose
This audio template should be chosen when the radio is used in a moderate ambient noise
environment where the sound pressure level is less than 79 dBSPL(C).
Example: The day to day indoor and moderate noisy outdoor environment.
• Indoor
This audio template should be chosen when the radio is used in the quiet indoor environment
where the ambient sound pressure level is less than 65 dBSPL(C).
Example: A business office environment.
• Outdoor, Noisy type1
This audio template should be chosen when the radio is used in a noisy street environment
where the ambient sound pressure level is around 85 dBSPL(C).
Example: Traffic noise environment
• Outdoor, Noisy type2
This audio template may be chosen when the radio is used in a low frequency background
noise environment where sound pressure level is around 85 dBSPL(C). This template is
optimized with respect to speech intelligibility.
Example: Port, airport, energy plant etc. environments
• Outdoor, Noisy type3
This audio template may be chosen when the radio is used in a low frequency background
noise environment where sound pressure level is around 85 dBSPL(C). This template is
optimized with respect to noise penetration.
Example: as Noisy type 2
• Outdoor, Harsh type1
This audio template should be chosen when the radio is used in a harsh noise environment
where sound pressure level is around 89 dBSPL(C). This template provides a compromise
between loudness and howling distance.
Example: as Noisy type 2
• Outdoor, Harsh type2
This audio template should be chosen when the radio is used in a harsh noise environment
where sound pressure level is around 89 dBSPL(C). This template is optimized with respect
to loudness at an expense of howling distance.
Example: as Noisy type 2
Note: Several Audio Profiles can be created based on the same template to cater to different use
cases for example:
• Outdoor, handheld
• Outdoor, shoulder worn
