Restoration of Click Degraded Speech and Music Based on High Order Sparse Linear Prediction KU Leuven
School-age hearing screening based on speech-in-noise perception using the digit triplet test KU Leuven
OBJECTIVES: This study aims to investigate the large-scale applicability of the Digit Triplet test (DTT) for school-age hearing screening in fifth grade elementary (5E) (9 to 12 years old) and third grade secondary (3S) (13 to 16 years old) school children. The reliability of the test is investigated as well as whether pass/fail criteria need to be corrected for training and/or age, and whether these criteria have to be refined with respect to ...
Missing sample estimation based on high-order sparse linear prediction for audio signals KU Leuven
© EURASIP 2018. The restoration of click degraded audio signals is important to achieve acceptable audio quality in many old audio media. Restoration by missing sample estimation based on conventional linear prediction has been extensively researched and used; however, it is hampered by the limitations of the linear prediction model. Recently, it has been shown that high-order sparse linear prediction offers better representation of music and ...
Development of a Dutch matrix sentence test to assess speech intelligibility in noise KU Leuven
OBJECTIVE: A Dutch matrix sentence test was developed and evaluated. A matrix test is a speech-in-noise test based on a closed speech corpus of sentences derived from words from fixed categories. An example is "Mark gives five large flowers." DESIGN: This report consists of the development of the speech test and a multi-center evaluation. STUDY SAMPLE: Forty-five normal-hearing participants. RESULTS: The developed matrix test has a speech ...
Exploring the sensitivity of speech-in-noise tests for noise-induced hearing loss KU Leuven
OBJECTIVE: Recently, the digit triplet test was shown to be a sensitive speech-in-noise test for early high-frequency hearing loss in noise-exposed workers. This study investigates if a further improvement is achieved when using a closed set of consonant-vowel-consonant (CVC) speech items with the same vowel, and/or a low-pass (LP) filtered version of the standard speech-shaped noise. DESIGN: Speech reception thresholds in noise were gathered ...
Efficient hearing screening in noise-exposed listeners using the Digit Triplet test KU Leuven
OBJECTIVES: Hearing screening in occupational medicine is generally based on pure-tone threshold audiometry. However, reliable and valid thresholds can only be obtained in a sound-proof room, using a high-quality, well-calibrated audiometer, and by a well-trained administrator. Thresholds also need to be determined for several audiometric frequencies. This makes the test time-consuming and expensive, which is not ideal for the screening of large ...
Noise exposure of care providers during otosurgical procedures KU Leuven
