What is a TYPE 3.2 Ear?
|
What is needed to use the Type 3.2 Ear?
|
The Type
3.2 Ear Simulator provides a controlled leak to simulate the average
real ear loss for telephone handsets which are held either firmly
(low leak version) or loosely (high leak version) against the human
ear.
Microtronix offers the Type 3.2 Ear solution for the following products:
Telephone Acoustic Tester
Wireline Phone Test System
IP-II Phone Test System
Custom Acoustic Applications
|
The Type 3.2 Ear solution
consists of hardware and software, and is used with products such
as the Telephone Acoustic Tester, IP-II Phone Test System, Wireline
Phone Test System or our Custom Acoustic Application.
The following is required to connect the Type 3.2 Ear to the Manual
Acoustic Fixture:
Pinna Simulator High Leak or Low Leak

When is the Type 3.2 Ear Required? |
Microtronix Manual Acoustic Fixture with Type 3.2 Ear
|
| The Type 3.2
Ear may be used for production or quality assurance testing to provide
a realistic ear leakage test environment. Microtronix recommends the
use of the Type 3.2 Ear in production and quality assurance testing
to the requirements of specifications such as ANSI/TIA-470-C, TIA/EIA-810-A,
TIA-920, GSM11.10 and others. Many of these standards require testing
with a Head and Torso Simulator (HATS), but for most production and
quality assurance testing environments this is not practical; testing
with the Type 3.2 Ear is a reasonable alternative that can provide
similar results. |

What are the Advantages of the Type 3.2 Ear Solution? |
|
|
The Microtronix Type 3.2 Ear solution
allows customers to test their handset products with a controlled
acoustic leak. Telephone designers need to select a leak-tolerant
transducer during the design phase of products intended to meet the
requirements of these standards. Testing these products with a Microtronix
Test System with the Type 3.2 Ear option will verify quality performance.
