Telephone Testing for R&D and Production
Interfaces to all types of phone
SoundCheck’s open interface means that your type of device, whether analog, digital, USB, cell or VoIP, can be connected to the SoundCheck system. SoundCheck supports third-party interface accessories that may be required for some types of phones.
Interfaces to all types of test transducers
SoundCheck’s built-in calibration tools completely support virtually all electroacoustic test platforms, such as mouth simulators, ear simulators, and Head and Torso Simulators
Listen offers a complete range of test accessories
Listen accessories include Microphones, AmpConnect, SoundConnect, and the Legato telephone test interface, which provides the electrical test circuits needed for analog telecommunications testing. Approved third-party test accessories can be bundled with your system These include microphones, acoustic calibrators, mouth simulators, ear simulators, and Head and Torso Simulators – with or without handset positioners,
Supports all Telephone Test Stimuli
Soundcheck accommodates virtually all telephone test stimuli, ranging from simple stimuli such as sine waves and noise to artificial, synthesized and real speech. SoundCheck can also accommodate composite source signals (e.g. consisting of a conditioning signal to trigger the voice activity detector, a measurement signal and a modulation segment). SoundCheck can meet current and likely future telephone test standards.
SoundCheck’s simple point and click test development interface makes it easy to build complex telephone tests, and a variety of pre-programmed analyses enable you to be up and running with industry standard tests fast. Whether you are testing to a telephone industry standard using a pre-programmed test sequence, building a test from scratch, or developing your own custom telephone test by modifying standard SoundCheck test sequences, test development is powerful, flexible and fast.
Includes telephone-test specific features
SoundCheck can accommodate all known standard loudness rating tests. Narrowband loudness rating curves are included, and as it allows custom curves to be imported, it is flexible enough to accommodate any new loudness rating standards that may be developed. Measurement of active speech level (ASL) is also available.
Testing Telephone Components and Accessories
Testing telephone receivers, speakers and microphones is essentially the same as testing loudspeakers and microphones. The main difference is in the specifications to which they are tested and the limits that are set. In addition, SoundCheck can also be used to test other smartphone components and accessories such as Bluetooth headsets, MP3 players, docking stations and headphones. Please refer to our other application notes for information on testing these smartphone components.
TIA Test Sequences
We offer test sequences written by a leading telecom test expert for testing to TIA470-C, TIA 820, TIA 920 and IEEE 1329 test standards. All major clauses of the standard are included in each package. Calibration, user prompts and the ability for the user to use the sequence as it stands or customize it make it simple to use and versatile for all telephone testing needs.
Testing Telephones with Background Noise
SoundCheck can be set up to test telephones in a noisy environment to simulate real life situations. In this configuration, SoundCheck controls a virtual environment in which multiple sound sources are simultaneously equalized and calibrated to simulate background noise.
Examples: How do our Customers use SoundCheck for Measuring Telephones?
These are just some of the telephone measurements that our customers are making:
- Measurement of speakerphone to TIA 920-A
- Measurement of frequency response, loudness rating and distortion of handset
- Measurement of dropout on a Bluetooth headphone
