Publisher: Multi-Science Publishing

Description

The considerable and growing interest in the phenomena of low frequency noise and vibration and their powerful effects on man, animals and the environment, spreads across several disciplines; studies of these topics are to be found at present in the periodical literature of acoustics, geophysics, architecture, civil and mechanical engineering, psychology and zoology.This quarterly journal brings together material which otherwise would be scattered: the journal is the cornerstone of the creation of a unified corpus of knowledge on the subject. Among the topics covered by the journal are: sources of infrasound and low frequency noise and vibration: detection, measurement and anlysis; propagation of infrasound and low frequency noise in the atmospere; propagation of vibration in the ground and in structures; perception of infrasound, low frequency noise and vibration by man and animals; effects on man and animals; interaction of low frequency noise and vibration: vibrations caused by noise, radiation of noise from vibrating structures; low frequency noise and vibration control: problems and solutions.

    ABSTRACT: A mathematical model is developed for the use of design engineers to analyze temperature-thickness coupling problem of a non-homogeneous isotropic visco elastic rectangular plate. Here, authors considered that temperature varies biparabolic i.e. parabolic in x– and parabolic in y– direction while thickness of plate varies linearly in one direction. The non-homogeneity of the plate’s material is characterized by assuming an exponential variation of poisson’s ratio of the plate’s material. The first two modes of time period and deflection are reported here for various combinations of frequency parameters i.e. nonhomogeneity constant, thermal gradient, taper constant and aspect ratio of the plate. Numerical results for time period and deflection for both the modes of vibration are shown in tabular form.

    ABSTRACT: It is important to understand whole body vibration (WBV) since it affects comfort and is important in worker health and performance. Although discomfort can be subjectively evaluated, the ISO 2631-1 standard predicts discomfort based on vibration magnitudes, frequencies and durations. The objective of this study was to determine whether the ISO 2631-1 prediction method produces similar results to self-reported discomfort levels during routine heavy machinery operations in the field. While working under normal conditions, 6 df seat-pan vibration data were recorded in construction, mining, and forestry vehicles. At 5-minute intervals, operators rated their discomfort based on the preceding minute of vibration exposure. Discomfort was predicted from the vibration total value for each corresponding one-minute vibration profile. Each industry showed consistent trends between the predicted and self- reported discomfort; however, there were different relationships between industries. Construction showed a weak positive relationship (r2=0.09) between predicted and self-reported discomfort values, whereas both forestry and mining showed no relationship. The predicted discomfort levels did not accurately represent self-reported discomfort; this is similar to some previous studies, but contrasts with other studies. This variability may be due to discrepancies with the prediction equations, or perhaps due to additional factors being incorporated into self-reported comfort measures, such as temperature, noise, and fatigue.

    ABSTRACT: Whole-body vibration (WBV) of mobile machines used in the steel making industry has not previously been quantified in six-degrees-of-freedom (6DOF). The purpose of this paper was to quantify 6DOF vibrations during the daily operating tasks of 5 commonly used mobile machines types used in the steel making and metal smelting industries. Vibration data were recorded from the chassis of five commonly used mobile machines using a MEMSense MAG3 triaxial accelerometer & gyroscope (MEMSense, SD, USA), and analyzed using custom MatlabTM code. Elevated values were observed at the chassis for crest factors, peak running root mean squared accelerations, and vibration total values, resulting in ISO 2631-1 (1997) comfort predictions ranging from Uncomfortable to Extremely Uncomfortable. Vibration dominant frequencies were generally between 1 and 8Hz. A second peak which occurred at approximately 27 Hz was observed for each vehicle in almost all axes. Occurring at a frequency that has the potential to produce negative health effects, this second peak was probably caused by the engine idling or running at low speeds. Field vibration profiles from this study have been used as inputs to a 6DOF robot for use in a corresponding laboratory study designed to optimize seat selection thus allowing the steel making and other similar industries to select operator seats based on industry specific field vibration characteristics.

    ABSTRACT: This field study aimed to evaluate the prevalence of annoyance and disturbance and the subjective perception of the sound environment due to noise, in an old and a new control room at a large paper mill. Working in a control room requires sustained attention and concentration and, in the case of error messages, rapid and correct decisions. In this study, the personnel's responses were collected by questionnaire, and detailed sound measurements were taken in both control rooms. The A-weighted sound pressure level in the new control room was 54.9 dB, a reduction from the 63.5 dB measured in the old room, and the C-weighted sound pressure level was 66.8 dB, a reduction from the 75.2 dB measured in the old room. The new control room was rated as being a less noisy environment; however, the personnel did complain about noise from other computers/equipment, radios, and the new laboratory.

    ABSTRACT: In order to investigate influences on assessment of interior truck sounds two experiments have been carried out with emphasis on the low frequency content. In the first experiment the participants were presented with recorded sound from the interior of a truck cabin, with different alterations of the low frequency content. In the second experiment the balance between low and high frequency content was altered for the recorded sounds. Three main dimensions important for the assessment of truck sounds were found: an Annoyance factor, a Wakefulness factor and a Quality factor. Additionally it was found that a well-suited spectral balance could improve positive impressions of truck sound
