“…The voice F 0 values of the present study were similar to those reported in Södersten et al [23] but somewhat lower than those reported in Lyberg Åhlander et al [14] and in Rantala et al [15]. There was a systematic although not large (5 Hz) increase in F 0 in the teachers from the first to the last lesson.…”

“…To the best of our knowledge, only 2 research groups, Echternach et al [22] and Södersten et al [23], used an accelerometer (VoxLog) similar to ours for activity noise level measurement during teaching. Both studies report 9 dB higher values for activity noise level than the present study.…”

“…Furthermore, variations in time window settings may have also influenced the differences. We used a 1-min time window, as did Södersten et al [23], whereas Echternach et al [22] used a 5-s time window. Possible variation in statistical methods could explain some of the differences: we used medians, while Södersten et al and Echternach et al used means.…”

“…Such a good speech-to-noise ratio during these lessons revealed a dilemma: from the children’s point of view, this finding was desirable and indicated that the voice of teacher was easily heard in the classroom (although the SNR may be worse at the students’ position, since the teacher’s sound level will likely be lower there) but, from the teacher’s point of view, the finding revealed raised voice use. It seemed possible that the teachers may adjust their voice to increase SNR at the listener’s position rather than at their own position and preferred to use their voice as required by their profession instead of more ergonomically [23]. A possible solution to this dilemma might be a compromise between a good listening acoustic [25] and a good speaking acoustic [30] environment.…”

“…The same proportion of teachers talked with raised voice levels, ≥86 dB (at 0.1 m), and no teacher used a relaxed level ≤74 dB (at 0.1 m). There have so far been no reliable reference values, especially for voice SPL recorded by means of a portable voice accumulator, although some data [22, 23] have been published. This study confirms the correlation between noise levels and voice loudness (voice SPL) as shown in both the laboratory environment [12] and field investigations [22].…”

Objective: Our interest was in how teachers’ voices behave during the delivery of lessons in core subjects (e.g., mathematics, science, etc.). We sought to evaluate the relationship between voice sound pressure level (SPL), vocal fundamental frequency (F₀), voice symptoms, activity noise, and differences therein during the first and the last lessons in core subjects of the day. Patients and Methods: The participants were 24 female elementary school teachers. Voice symptoms were evaluated by questionnaire. The data were recorded on 2 portable voice accumulators (VoxLog) from the first and last lessons of the day. The versions of accumulators differed by frequency weighting; therefore, the analysis and the results of noise and voice SPL were treated separately: unweighted (group 1) and A-weighted (group 2). Results: Difference in voice SPL followed difference in activity noise. F₀ increased between the first and last lessons. Correlations were found between differences in the noise and the voice symptoms of tiredness and dryness. Irritating mucus was associated with high F₀ during the first lesson. Conclusion: An apparent increase in voice loading due to the activity noise was observed during lessons in core subjects. Collaboration between specialists in voice and acoustics and teachers and pupils is needed to reduce this voice loading.

Introduction Vocal loading capacity is an important aspect of vocal health and is measured using standardized vocal loading tests. However, it remains unclear how vocal fold oscillation patterns are influenced by a standardized vocal loading task. Methods 21 (10 male, 11 female) vocally healthy subjects were analyzed concerning the dysphonia severity index (DSI) and high speed videolaryngoscopy (HSV) on the vowel /i/ at a comfortable pitch and loudness before and after a standardized vocal loading test (10 min standardized text reading, at a level higher than 80 dB (A) measured at 30 cm from the mouth). Results Changes in DSI were statistically significant, diminishing by 1.2 points after the vocal loading test, which was mainly caused by an increase of the minimum intensity. However, the pre-post comparison of HSV derived measures failed to show any statistically significant changes. Conclusion It seems necessary to analyze the effects of a standardized vocal loading test on vocal fold oscillation patterns with respect to softest phonation and phonation threshold pressure rather than comfortable pitch and loudness. Level of evidence 2c Keywords Vocal loading • High speed imaging • Dysphonia severity index • Minimal intensity
