This paper, the second in a series of two, presents the results of a rock mechanics evaluation of the Weeks Island dome salt mine. The purpose of the evaluation was to assess the structural stability of the old mine workings in conjunction with a proposed new deeper mine level during the use of the facility for the long-term storage of crude oil under the Federal Energy Administration’s Strategic Petroleum Reserve Program. The scope of the work involved laboratory testing of the strength and deformational characteristics of the rock salt; determination of a minimum web (or sill) thickness between the old workings (within which crude oil would be stored) and a proposed new mine level development below; and assessment of the effects of crude oil emplacement and withdrawal on the mine stability, as related to both the old workings and the proposed new mine level development. The finite element results, wherein use was made of the strength and deformation properties of the salt from the laboratory tests, indicated that a minimum sill thickness of 90 m (300 ft) should be maintained between the old mine workings and the new level development. Furthermore, the emplacement and withdrawl of crude oil from the old workings will have little influence on pillar and sill stabilities for the entire mine, including the proposed lower level development. The only noticeable effect could, perhaps, be obtained in the creep rate due to changing stress conditions.

Purpose Misophonia is a sound tolerance disorder condition in certain sounds that trigger intense emotional or physiological responses. While some persons may experience misophonia, a few patients suffer from misophonia. However, there is a dearth of literature on audiological assessment and management of persons with misophonia. The purpose of this report is to discuss the assessment of misophonia and highlight the management option that helped a patient with misophonia. Method A case study of a 26-year-old woman with the complaint of decreased tolerance to specific sounds affecting quality of life is reported. Audiological assessment differentiated misophonia from hyperacusis. Management included retraining counseling as well as desensitization and habituation therapy based on the principles described by P. J. Jastreboff and Jastreboff (2014). A misophonia questionnaire was administered at regular intervals to monitor the effectiveness of therapy. Results A detailed case history and audiological evaluations including pure-tone audiogram and Johnson Hyperacusis Index revealed the presence of misophonia. The patient benefitted from intervention, and the scores of the misophonia questionnaire indicated a decrease in the severity of the problem. Conclusions It is important to differentially diagnose misophonia and hyperacusis in persons with sound tolerance disorders. Retraining counseling as well as desensitization and habituation therapy can help patients who suffer from misophonia.

Purpose The purpose of this article is to present a client-centered model of counseling that integrates information and personal adjustment counseling. Research has indicated that audiologists are more comfortable with counseling that is information based than with personal adjustment counseling. The prevailing model of diagnosis appears to be the medical model in which, first, a case history is taken, then testing and, finally, counseling. This model lends itself to audiologist as expert and the counseling as a separate entity based on information and advice. Further research has indicated parents retain little of the information provided in the initial examination because of their heightened emotions. This article presents a client-centered model of diagnosis in which information is provided within an emotionally safe context, enabling the parents to express their feelings and have the ability to control the flow of information. The ultimate purpose of a client-centered model is to empower parents by making them active participants in the diagnostic process rather than passive recipients. Conclusion The client-centered model has wide implications for the diagnostic process as well as for the training of students.
