During a three year-period, the participants of a NATO Science for Peace project performed ambient noise measurements inside buildings in four European countries. This paper reports the results relevant to reinforced concrete (RC) buildings with height in the range 1-20 floors. The total number of such buildings surveyed is 244. The most striking feature is the similarity of the height-period relationships in the four countries, which allowed the treatment of the all measurements as a single database. We found no significant correlation with other variables, and calculated a regression that is very similar to other empirical height-period relationships and quite different from code provisions and theoretical models.

HBO and IT steroid therapy could be successfully used as salvage therapies in patients with sudden deafness. Further study is needed to demonstrate superiority of one of the treatments.

A proper classification of voice pathology is required for didactic reasons, and also to assist a clinician in establishing the ‘primary diagnosis’, i.e., an initial voice disorder in a particular patient. In spite of a frequent etiologic overlapping between organic and functional voice disorders, it is useful to keep these two basic pathologic categories in clinical practice. A revised clinical classification of voice disorders is suggested, including several newly described voice disturbances. These are the syndrome of inappropriate vocal pitch (organic), psychogenic superimposition and false placement of the voice (functional).
