DeJonckere P, Lebacq J
Bioengineering (Basel) . 2025 Feb; 12(2). PMID: 40001675
Voice onset is the sequence of events between the first detectable movement of the vocal folds (VFs) and the stable vibration of the vocal folds. It is considered a critical...

DeJonckere P, Lebacq J
Int Arch Otorhinolaryngol . 2023 Aug; 27(3):e499-e510. PMID: 37564477
 The question as to whether occupational noise exposure causes symmetrical or asymmetrical hearing loss is still controversial and incompletely understood.  Two electrophysiological methods (cortical evoked response audiometry: CERA and auditory...

Pharmaceuticals (Basel) . 2023 Jun; 16(6). PMID: 37375779
Osteogenesis imperfecta (OI) is a genetic disorder of connective tissue characterized by spontaneous fractures, bone deformities, impaired growth and posture, as well as extra-skeletal manifestations. Recent studies have underlined an...

DeJonckere P, Lebacq J
J Voice . 2020 Oct; 36(5):608-621. PMID: 33004227
Mechanical impact stress on the vocal fold surface, particularly when excessive, has been postulated to cause the so-called phonotraumatic tissue lesions, such as nodules and polyps. The collision stress between...

Dejonckere P, Lebacq J
J Voice . 2019 Sep; 35(1):156.e23-156.e32. PMID: 31481279
The most frequently observed type of voice onset in spontaneous speech in normal subjects is the soft onset, and it may be considered as the "physiological" onset. It starts from...

DeJonckere P, Lebacq J
J Voice . 2019 Jan; 34(4):645.e19-645.e39. PMID: 30658875
Intraglottal pressure is the driving force of vocal fold vibration. Its time course during the open phase of the vibratory cycle is essential in the mechanics of phonation, but measuring...

DeJonckere P, Lebacq J, Titze I
J Voice . 2017 May; 31(6):649-661. PMID: 28495329
Intraglottal pressure is the driving force of vocal fold vibration. Theoretically, simultaneous quantification of glottal area and transglottal airflow allows the calculation of the intraglottal pressure waveform during a single...

Lebacq J, Schoentgen J, Cantarella G, Bruss F, Manfredi C, Dejonckere P
J Voice . 2017 Mar; 31(5):550-556. PMID: 28320627
Purpose: Smartphone technology provides new opportunities for recording standardized voice samples of patients and transmitting the audio files to the voice laboratory. This drastically improves the achievement of baseline designs,...

J Voice . 2015 Dec; 30(6):769.e9-769.e18. PMID: 26706750
Introduction: Inspiratory phonation (IP) means phonating with inspiratory airflow. Some vocalists remarkably master this technique, to such an extent that it offers new dramatic, aesthetic, and functional possibilities in singing...

DeJonckere P, Lebacq J, Bocchi L, Orlandi S, Manfredi C
Logoped Phoniatr Vocol . 2014 Jan; 40(1):44-54. PMID: 24456119
This article presents a novel application of the 'single line scanning' of the vocal fold vibrations (kymography) in singing pedagogy, particularly in a specific technical voice exercise: the 'messa di...
