“…This difference could be explained on the basis of the number of instructions about voice style: fewer instructions will correspond to a larger dynamic range of the voice across styles. Bottalico et al (2015), in a similar experiment that involved instructing talkers to use three voice styles (soft, normal, and loud), found a smaller dynamic range than the one reported in the present study (6.8 dB between loud and normal, and 7.8 dB between normal and soft). A second possible explanation could be that the dynamic range of speech in noisy conditions might tend to be smaller than the range in quiet conditions (Bottalico et al, 2015).…”

This might occur because speech produced in a noisy environment will be higher in level than speech produced in a quiet environment (Lombard effect), all else being equal.…”

Vocal effort is a physiological measure that accounts for changes in voice production as vocal loading increases. It has been quantified in terms of sound pressure level (SPL). This study investigates how vocal effort is affected by speaking style, room acoustics, and short-term vocal fatigue. Twenty subjects were recorded while reading a text at normal and loud volumes in anechoic, semi-reverberant, and reverberant rooms in the presence of classroom babble noise. The acoustics in each environment were modified by creating a strong first reflection in the talker position. After each task, the subjects answered questions addressing their perception of the vocal effort, comfort, control, and clarity of their own voice. Variation in SPL for each subject was measured per task. It was found that SPL and self-reported effort increased in the loud style and decreased when the reflective panels were present and when reverberation time increased. Self-reported comfort and control decreased in the loud style, while self-reported clarity increased when panels were present. The lowest magnitude of vocal fatigue was experienced in the semi-reverberant room. The results indicate that early reflections may be used to reduce vocal effort without modifying reverberation time.

Summary Speakers increase their vocal effort when their communication is disturbed by noise. This adaptation is termed the Lombard effect. The aim of the present study was to determine whether this effect has a starting point. Hence, the effects of noise at levels between 20 and 65 dB(A) on vocal effort (quantified by sound pressure level) and on both perceived noise disturbance and perceived vocal discomfort were evaluated. Results indicate that there is a Lombard effect change-point at a background noise level (Ln) of 43.3 dB(A). This change-point is anticipated by noise disturbance, and is followed by a high magnitude of vocal discomfort.

Tačiau trypimas, spintelių durų varstymas ar kamuolio bumsėjimas sukelia papildomą aplinkos triukšmą, prie kurio mokiniai taiko savo balso galimybes ir tokiu būdu pasiekiamas žymiai didesnis triukšmo lygis, nei tik kalbė-jimas ramioje aplinkoje.…”

Raktažodžiai: triukšmo lygis, mokiniai, mokyklos vidinė aplinka. SantraukaLietuvoje visuomeninės paskirties pastatų patalpose, kuriose vyksta mokymas ir (ar) ugdymas, triukš-mo lygį valstybė reglamentuoja riboti iki 55 dB(A Triukšmo patologinis laipsnis priklauso nuo jo intensyvumo ir poveikio trukmės. Itin pavojingas triukšmas, veikiantis naktį besiilsintį žmogų. Žmonės, gyvenantys šalia intensyvios eismo gatvės, kurioje naktį sklinda 55 ir daugiau decibelų triukšmas, dažniau skundžiasi padidėju-siu kraujospūdžiu, padidėja miokardo infarkto, migrenos rizika, kraujyje padidėja cholesterolio kiekis [3].Klausos nuovargis išsivysto ilgesnį laiką (kelias valandas ar visą darbo pamainą) veikiant intensyviam triukšmui, kuris didesnis nei 85 dB. Jei klausa perdirginama ir klausos nuovargis kartojasi kasdien, tai ilgainiui gali vystytis progresuojantis klausos susilpnėjimas, kuris dažniausiai baigiasi profesiniu neurosensorinės kilmės kurtumu [4,5]. Nuolatinis triukšmas sukelia klausos nervinių ląstelių metabolinį išsekimą. Triukšmo pirmiausia yra veikiamos vidinės ausies sraigėje esančios sensoepitelinės ląstelės, suyra šių ląstelių segmentai, o vėliau degeneruoja klausos nervas dėl mielinio dangalo degeneracinių procesų [6,7]. Triukšmo nespecifinis poveikis organizmui pasireiškia funkciniu centrinės ir vegetacinės nervų sistemos pakenkimu -veikiamos širdies ir kraujagyslių sistemos, kiek mažiau kvėpavimo sistema, sutrikdoma medžiagų apykaita
