Electroacoustic Measurements on Telephones

Description

This seminar teaches the fundamentals of electroacoustic measurement and how to apply them to the measurement of telephones, mobile phones, and other devices with telephone functions. Specialised principles, techniques and vocabulary used in measuring the electroacoustic transmission of analogue, digital, cellular, and other telephones are covered. Methods specified in the ITU-T (formerly CCITT), ETSI, IEEE, TIA standards are explained.
You will be supplied with practical suggestions for the selection, calibration, and use of microphones, ear simulators, mouth simulators, and fixtures for testing handset, headset, and hands-free (loudspeaking)telephones.
The course also includes perceptually based analysis methods, an overview of acoustic modelling, how to interpret microphone and receiver data sheets, and practical tips for telephone designers.
Many measurements will be demonstrated, and actual measurement results will be presented. Understanding the principles and interpretation of measurements will be emphasised.

Objectives

To teach the fundamentals of electroacoustic measurements and how to apply them to the measurement of telephones, mobile phones and other devices with telephone functions.

Participants

This course is especially designed for engineers, technical managers and engineering technicians working in design, R&D, QC or production line testing, within the telecommunication industry.
