As wind turbines get larger, worries have emerged that the turbine noise would move down in frequency and low-frequency cause annoyance for neighbors. The emission from 48 with nominal electric power up to 3.6 MW is analyzed discussed. relative amount of higher large (2.3–3.6 MW) than small (≤ 2 MW), difference statistically significant. can also be expressed as a downward shift spectrum approximately one-third an octave. A further similar size suggested future 10-MW range. Due air...
Sound transmission to the eardrum from various points in external ear was measured by means of probe microphone technique. Twelve human subjects participated, and three directions sound incidence were included. For major part audio frequency range proved independent direction at centerline canal, including entrance (open or blocked). The results further suggested that region with extends some millimeters outside plane. free field divided into a directional-dependent two...
Abstract Objective. In 1998, the Danish Society for Head and Neck Oncology decided to conduct a nationwide survey at five head neck oncology centers with aim of evaluating surgical outcome salvage laryngectomy after radiotherapy special emphasis on identifying factors that could contribute development pharyngocutaneous fistulae. Patients. A total 472 consecutive patients undergoing postirradiation in period July 1, 1987–June 30, 1997 were recorded Denmark. Age ranged from 36 84 years, median...
Abstract Twenty-one properties in the Otago region of South Island New Zealand were surveyed for presence gross lesions due to Mycobacterium bovis infection feral cats (Felis catus), ferrets (Mustela furo) and stoats erminea) during 1993 1994. In total, 1293 cats, ferrets, weasels nivalis) examined tuberculous lesions. The selected according history incidence bovine tuberculosis their cattle herds. Sixteen infected trapped areas that endemic five non-endemic considered be free from cattle....
Thresholds of hearing Were determined in pressure field at frequencies from 4 Hz to 125 Hz. At the 4–25 thresholds were found that are lower middle range already reported by other investigators. 25 1 kHz have been free same method and using subjects. The two investigations overlap Hz, this results almost identical. differences below dB, except 63 where difference was 2.5 dB. None significant a t-test.

Contours of equal annoyance were determined for pure tones in the frequency range 4 – 31.5 Hz. The curves show a narrowing dynamic ear at low frequencies. same pattern is seen loudness curves, and results support theory that infrasound closely related to sensation. Annoyance ratings 1/3 octave noise did not deviate from with sound pressure level. Combinations audio infrasonic general given rating close or slightly above most annoying individual conditions. For proposed G1-weighting curve...
A survey of complaints about infrasound and low frequency noise has been carried out. 198 persons reported their troubles in a questionnaire. Their verbal reports often described the sound as deep humming or rumbling, if coming from distant idling engine truck pump. Nearly all respondent's sensory perception sound. In general they that perceived with ears, but many mention also vibration, either body external objects. The disturbs irritates during most activities, consider its mere presence...
Contours of equal loudness were determined in the frequency range 2–63 Hz and 20–100 phon. The curves run almost parallel infrasonic much closer than audio region. Infrasound only a few dB above hearing threshold will therefore seem loud possibly annoying. subjects 20 normal students aged between 18 25, psychometric method was based on maximum-likelihood estimation functions.
Due to standing waves, the sound pressure level within a room may vary as much 20–30 dB at low frequencies. Principal properties of low-frequency in rooms are illustrated by simulations, and distributions well performance Swedish Danish measurement methods studied measurements three rooms. For assessment annoyance, mainly areas with high levels interest, since persons present such not helped existence lower other areas. The that is exceeded 10% (L 10 ) proposed rational objective target for...
Abstract Ifriqiya (roughly Tunisia and eastern Algeria) is believed to have played a significant role in the diffusion of ceramic glazed technologies into other regions Western Mediterranean. However, due limited analysis on North African ceramics, its technology transfer remains poorly understood. This paper uses SEM–EDS petrographic analyses understand employed production Tunisian ceramics through study 30 polychrome from medieval settlement at site Chimtou (ancient Simitthus), Tunisia,...
