SIMPLIFIED MATRIX TEST

The Simplified Matrix Test is an audiometric test to determine the speech recognition threshold in quiet or in noise for children from the age of four, adults, CI users and people with a reduced word span. As with the OLKISA, simplified sentences of the respective matrix test are used as speech material. The sentences have the form number word - adjective - noun with a random combination from an inventory of 21 words in total (e.g. "Three green shoes"). The design of the test prevents memorization of the sentences, so the Simplified Matrix Test can be repeated as many times as needed. For this reason, it is particularly well suited for recurrent measurements in the fitting of hearing aids or the adjustment of cochlear implants.

• 10 test lists with 7 sets each
• 20 test lists with 14 sentences each
• automatic, adaptive level control for measuring speech recognition thresholds
• measurement of speech recognition thresholds between 20% and 80% intelligibility possible
• measurement with continuous noise possible
• measurement with answer input by patient possible

Measurement of speech intelligibility threshold

• with children
• with adults with reduced word span
• with CI users
• when short measurement duration is a decisive criterion
• in studies with many measurement repetitions

• Suitable for children, CI users, and people with a reduced word span, due to shortened sentences
• High accuracy
• Short measurement duration
• Can be repeated as often as desired
• Measurement at rest or in noise
