    ABSTRACT: Among underground coal miners, hearing loss remains one of the most common occupational illnesses. In response to this problem, the National Institute for Occupational Safety and Health (NIOSH) Office of Mine Safety and Health Research (OMSHR) conducts research to reduce the noise emission of underground coal-mining equipment, an example of which is a roof bolting machine. Field studies show that, on average, drilling noise is the most significant contributor to a roof bolting machine operator's noise exposure. NIOSH OMSHR has determined that the drill steel and chuck are the dominant sources of drilling noise. NIOSH OMSHR, Corry Rubber Corporation, and Kennametal, Inc. have developed a bit isolator that breaks the steel-to-steel link between the drill bit and drill steel and a chuck isolator that breaks the mechanical connection between the drill steel and the chuck, thus reducing the noise radiated by the drill steel and chuck, and the noise exposure of the roof bolter operator. This paper documents the evolution of the bit isolator and chuck isolator including various alternative designs which may enhance performance. Laboratory testing confirms that production bit and chuck isolators reduce the A-weighted sound level generated during drilling by 3.7 to 6.6 dB. Finally, this paper summarizes results of a finite element analysis used to explore the key parameters of the drill bit isolator and chuck isolator to understand the impact these parameters have on noise.

    ABSTRACT: In this paper, active control of harmonic sound transmission through an acoustically baffled, rectangular, simply supported double panel partition has been analytically studied. Weighted sum of spatial gradients (WSSG) control metric of the radiating panel is minimized to attenuate multiple acoustic sound radiation modes and the results are compared with the minimization of volume velocity. A piezoceramic actuator (PZT) is attached on one side of the panel surface, and the optimal magnitude and phase of the voltage supplied to the PZT for minimizing WSSG and volume velocity at the error sensor locations are calculated using a simple-gradient based algorithm. Also, acoustic source arrangements are considered in the air cavity simultaneously with the structural control to further attenuate the transmitted sound power. Numerical results of sound power transmission ratio and averaged total kinetic energy of panels indicate that PZT should be placed on the incident panel to minimize the control quantities on the radiating panel. Combined WSSG and cavity control is able to control multiple acoustic radiation modes and the cavity modes and, thereby, accomplishes better attenuation in a wide frequency band.

    ABSTRACT: Risk perception plays an important role in a person's decision to wear hearing protection to reduce the occurrence of noise induced hearing loss. Therefore, as part of the safety training for a worksite, it is important to educate workers about the potential sources of noise exposure at the worksite so that the workers are aware of the risk. However, teaching a workforce with a range of educational and language skill levels about the risk of noise at the workplace can be a challenge. Instructing people that sources of noise such as machinery are loud may not effectively communicate to people that they could be exposed to noise which is loud enough to damage their hearing. Furthermore, not all of the sources of noise at the worksite may be known or included in the safety training, potentially leading the workers to believe that they are not exposed to high noise emission levels when they actually are at the worksite. This paper describes a measurement method called video dosimetry which combines images taken with a wearable camera with sound pressure levels measured using a dosimeter to create first person videos. The videos show the actions the person wearing the camera was engaged in at the worksite and the corresponding exposure levels. This information can help safety advisors to identify the noise exposure risk while engaged in common actions at the worksite. Furthermore, the videos based on first person images represent an engaging tool for educating at risk workers about the noise exposure levels associated with common activities occurring in the worksite.

    ABSTRACT: This paper investigates the measurement of the radiation efficiency of complex structures with two constructions: metallic (flat and stiffened aluminum panels) and sandwich composite (honeycomb core). Two measurement methods are compared. The first is direct and is based on the simultaneous measurement of the vibration and acoustic response of the freely hanged structure in an anechoic room. The second is indirect and uses a statistical energy analysis (SEA) based model of the test article freely hanged in a reverberant room. For the latter two implementations are compared. The first is based on the SEA formulation, when only the test article is excited. The second is an inverse technique based on the SEA formulation, when both the test article and the reverberant room are excited. All methods are compared to analytical or numerical predictions. Results show that the experimental radiations efficiencies are in good agreement with theory for the studied constructions, especially when the inverse SEA method is used.

    ABSTRACT: This paper presents the objective method to evaluate the subjective evaluation of the pulling sound of the seat belt. The physical quantification is required to objectively evaluate the subjective response of the pulling sound. This is called the “sound quality metric.” The sound quality metric should be correlated with the subjective rating of the pulling sound. In this paper, not only is the sound quality metric extracted from the measured interior sound when a passenger pulls the seat belt but also the subjective evaluation is performed for the pulling sound of the seat belt in the 18 vehicles. The pulling sound index is developed through a linear regress analysis of the sound quality metric and the subjective rating. The developed index is used for the objective evaluation of the subjective evaluation of the pulling sound of a seat belt with after modifications of seat belt components.

    ABSTRACT: Transportation noise consists of noise events, which come from moving aircrafts, trains, ships, boats and road vehicles. The noise of an isolated sound event is assessed by short term measurement of the sound exposure level, LAE. On the other hand, much legislation and many regulations and guidelines employ the day and the night average sound level, LAeqT, with needs long term measurements. It is shown how to estimate the mean LAeqT and its uncertainty from a representative sample of LAE and traffic flow records. Non-Gaussian distribution of LAeqT is assumed. For illustrative purposes, aircraft noise measurements were carried out. With any type of transportation noise, the presented methods are restricted to the extrapolation of noise events measurements at discrete monitoring stations from where the data comes.

    ABSTRACT: Based on principle of structural dynamics, the utility of excitation force and transferred boundary condition method is demonstrated by the vibration analysis of an equipment-base system. By constructing a “virtual force” while maintaining the consistency of transferred boundaries of structure with dynamic parameters locally unknown, transferred boundary similarity method (TBSM) is proposed to obtain the structural dynamic response with given transferred boundary conditions with structural dynamic parameters locally unknown. The effectiveness of TBSM is also verified. On that basis, TBSM is applied to the prediction of a ship's underwater vibration and sound radiation. The underwater sound radiation characteristic of a ship is analyzed. Result shows that the underwater vibration and sound radiation of a ship are highly related with location and frequency of excitation. On one hand, sound radiation from the ship is mainly concentrated in the vicinity of excitation of the middle and aft region of the ship, followed by aft and bow. On the other hand, the underwater sound radiation is more uniformly distributed along the ship length at low frequency band, while the inhomogeneity and directivity gradually increase as the excitation frequency increases.

    ABSTRACT: This study is concerned with the theory and application of a tuneable dynamic absorber. The dynamic characteristics of the tuneable dynamic absorber are discussed in terms of the mass ratio, natural frequency of the main structure, natural frequency of a dynamic absorber and excitation frequency. We proposed a semi-active dynamic absorber with a natural frequency that can change through the use of repulsive forces produced by permanent magnets and electromagnetic forces induced by current flowing through a coil. A simple active control algorithm is implemented in the LabView software and the experimental results showed that when the proposed semi-active dynamic absorber is used with the active control algorithm, the vibrations of a structure can be more effectively suppressed than when a passive dynamic absorber with a fixed natural frequency is used.
