US 2026/0256384 A1 · AN INTEGRATED DIGIT IN NOISE TEST TO EVALUATE HEARING AND COGNITIVE FUNCTION

Abstract

A testing method of testing a participant's ability to detect or understand speech, and evaluate hearing, speech understanding and processing, and cognitive function. The method includes: (a) audibly presenting a series of 2 digits, 3 digits, 4 digits, 5 digits, in random or fixed orders, to both ears or a first ear of a participant in quiet or in noise at a fixed or varied. The digits can be in any language; (b) repeating the same procedures as (a) to a second ear (c) recording digits or digit sequences identified correctly by the participant; and (d) recoding reaction time to repeat digits, (e) calculating scores based on the percentage of digits or digit sequences repeated correctly by the participant or the difference in level between speech and noise to yield 50% of the digit sequences being identified correctly.

A method of testing a participant's ability to accurately detect speech in the presence of background noise includes:

(a) audibly presenting a series of 2 digits, 3 digits, 4 digits and/or 5 digits, in random or fixed orders, to a first ear of a participant in quiet or in noise at a fixed or varied signal-to-noise ratios (SNRs), (b) audibly presenting a series of 2 digits, 3 digits, 4 digits and/or 5 digits, in random or fixed orders, to a second ear of a participant in quiet or in noise at a fixed or random signal-to-noise ratios (SNRs), wherein the digits are presented in a language native to the participant or in which the participant is fluent, (c) recording digits or digit sequences identified correctly by the participant and (d) calculating scores based on the percentage of digits or digit sequences repeated correctly by the participant or the difference in level between speech and noise to yield 50% of the digit sequences being identified correctly.

a speaker measuring device, comprising:
a first pairing connection module;
a first display configured to show a sequence of characters or numbers serving as test data;
and
a first signal transmitting module configured to transmit the test data via the first pairing connection module;
and
a listener measuring device, comprising:
a second pairing connection module configured to electrically communicate with the first pairing connection module;
a second display configured to show an indicator signal and display a virtual keypad;
a receiver configured to receive the test data from the speaker measuring device;
an audio recorder configured to record environmental sound data;
a testing recorder configured to record a test response inputted from the virtual keypad;
and
a scoring module configured to compare the test response with the test data to generate score data.
