Telephone Testing – Advanced

This webinar explains why and how to use advanced test signals such as speech and pulsed noises to measure frequency response and distortion in complex devices. It includes details about interfacing to analog, digital, cellular, and VoIP phones. SoundCheck sequences which test to TIA and IEEE standards are also discussed. John Bareham, Consultant in Electroacoustics. […]

Telephone Testing – The Basics

This recorded webinar is an excellent introduction to the measurements and system setups common to almost all telephone standards. This includes measurement of send, receive, sidetone, and echo, as well as loudness ratings. The techniques discussed in this webinar apply to handset, headset, and speakerphone functions of analog, digital, cellular and VoIP phones. John Bareham, […]

Testing to the TIA-920-A Telephone Test Standards Using SoundCheck

A demonstration of how wideband digital phones can be tested to TIA-920-A, a comprehensive US standard for measuring wideband digital phones. The webinar demonstrates the physical setup, and shows a complete test in SoundCheck, from calibration to final result. Presented by John Bareham, Consultant in Electroacoustics. Status: Recorded.

Perceptual Rub & Buzz

This sequence uses the CLEAR algorithm for perceptual Rub & Buzz measurement to detect AUDIBLE Rub & Buzz. It uses a simplified auditory perceptual model to measure the loudness of Rub & Buzz distor­tion in phons rather than the more traditional dB SPL and % distortion units. These better identify whether distortion due to manufacturing […]

New Bluetooth Interface

The New BTC-4148 enables Bluetooth devices to be accurately tested in SoundCheck® by offering full control over the Bluetooth connection. Accurately measuring Bluetooth devices is challenging. The Bluetooth protocol is a dynamic and adaptive system that provides devices with many options and parameters that are normally negotiated and set in an invisible manner. Using typical […]
