“…This is in contrast with recent findings by Yiu and Yip. 17 In a laboratory experiment, those authors investigated the effects of different background noise conditions on healthy speakers' voice during a 3-to 5-minute monologue with the use of an APM. Irrespective of gender, high background noise levels were associated with F0…”

Objectives: (1) To investigate music theory teachers' professional and extra-professional vocal loading and background noise exposure, (2) to determine the correlation between vocal loading and background noise, and (3) to determine the correlation between vocal loading and self-evaluation data.Methods: Using voice dosimetry, 13 music theory teachers were monitored for one workweek.Parameters analysed were voice SPL, F0, phonation time, vocal loading index (VLI) and noise SPL.Spearman's correlation was used to correlate vocal loading parameters (voice SPL, F0 and phonation time) and noise SPL. Each day, subjects self-assessed their voice using visual analogue scales. VLI and self-evaluation data were correlated using Spearman's correlation.Results: Vocal loading parameters and noise SPL were significantly higher in the professional than in the extra-professional environment. Voice SPL, phonation time and females' F0 correlated positively with noise SPL. VLI correlated with self-assessed voice quality, vocal fatigue and amount of singing and speaking voice produced. Conclusions:Teaching music theory is a profession with high vocal demands. More background noise is associated with increased vocal loading and may indirectly increase the risk for voice disorders.Correlations between VLI and self-assessments suggest that these teachers are well-aware of their vocal demands and feel their effect on voice quality and vocal fatigue. Visual analogue scales seem to represent a useful tool for subjective vocal loading assessment and associated symptoms in these professional voice users.

“…Finally, background noise level may also influence vocal loading, as it automatically causes speakers to increase their voice SPL and F0 or modulate spectral aspects. 16,17 workday. This allows one to present an authentic picture of both professional and extra-professional vocal demands.…”

“…High noise levels around and above 70 dBA are common in many communicationand vocally-demanding workplaces such as schools and preschools (Shield et al, 2015;Sjödin, Kjellberg, Knutsson, Landström, & Lindberg, 2012). To enhance the audibility of the voice in loud environmental noise, the speaker typically increases the voice SPL, along with increased fo which may result in hyperfunction (Garnier & Henrich, 2014;Hillman et al, 1989;Holmberg et al, 2003;Södersten et al, 2005;Titze, 1989a;Yiu & Yip, 2016). A systematic review by Cantor Cutiva et al (2013) revealed that high environmental noise levels, and the use of high voice SPL, are among the most common risk factors for voice disorders in teachers.…”

“…Activity noise disturbs speech communication and may interfere with performance and wellbeing (Astolfi & Pellerey, 2008;Banbury & Berry, 2005;Lundquist, Holmberg, & Landström, 2000;Shield & Dockrell, 2008). To maintain speech intelligibility, and to avoid the speaker having to increase voice SPL, conversation should be kept below 50-55 dBA (Yiu & Yip, 2016). Increased voice SPL is required at 70 dBA, and at 80-85 dBA the speaker must shout to be heard at 1 meter (Arlinger, 1999; The Swedish Work Environment Authority's provisions for noise, AFS 2005:16).…”

“…Lombard speech generally refers to several modifications to vocal characteristics (e.g., changes in loudness, pitch, and spectral tilt) in the context of elevated background noise levels. These effects have been observed in controlled laboratory settings and naturalistic settings that are known to induce Lombard speech [6,[12][13][14][15]. Characterizing background noise levels and Lombard speech in naturalistic environments is of critical importance to clinical voice assessment using ambulatory monitoring technology.…”

Wireless Neck-Surface Accelerometer and Microphone on Flex Circuit with Application to Noise-Robust Monitoring of Lombard Speech

Ambulatory monitoring of real-world voice characteristics and behavior has the potential to provide important assessment of voice and speech disorders and psychological and emotional state. In this paper, we report on the novel development of a lightweight, wireless voice monitor that synchronously records dual-channel data from an acoustic microphone and a necksurface accelerometer embedded on a flex circuit. In this paper, Lombard speech effects were investigated in pilot data from four adult speakers with normal vocal function who read a phonetically balanced paragraph in the presence of different ambient acoustic noise levels. Whereas the signal-to-noise ratio (SNR) of the microphone signal decreased in the presence of increasing ambient noise level, the SNR of the accelerometer sensor remained high. Lombard speech properties were thus robustly computed from the accelerometer signal and observed in all four speakers who exhibited increases in average estimates of sound pressure level (+2.3 dB), fundamental frequency (+21.4 Hz), and cepstral peak prominence (+1.3 dB) from quiet to loud ambient conditions. Future work calls for ambulatory data collection in naturalistic environments, where the microphone acts as a sound level meter and the accelerometer functions as a noise-robust voicing sensor to assess voice disorders, neurological conditions, and cognitive load.
