Due to the demanding acoustic conditions in physical education lessons and the related problems with health and academic success, the aim of this study was to examine the acoustic conditions of teaching in sport halls in Slovenia. Thirtyfive sport halls were selected, reflecting four types of school sport halls grouped according to the period of their construction. The reverberation time was me...

In countercurrent flow absorption columns and trickle beds, if either the liquid or gas flow is too high the column becomes flooded with the liquid. Flooding is accompanied by a dramatic increase in pressure, resulting in inefficient operation and potential damage to equipment. To optimize efficiency, however, it is desirable to operate as close to flooding as possible. This article discusses t...

A shopping promenade that incorporates six cinema halls with capacities ranging from 150 to 310 locations has been built in the city of Mar del Plata, Argentina. The authors of this project were the architects Mariani, Pérez Maraviglia and Cañadas. The employer of the project was Florencio Aldrey Iglesias, who has a long and recognized trajectory both locally and nationally. The place chosen by...

OBJECTIVE To compare the efficacy and feasibility of teleaudiometry with that of sweep audiometry in elementary school children, using pure-tone audiometry as the gold standard. METHODS A total of 243 students with a mean age of 8.3 years participated in the study. Of these, 118 were boys, and 125 were girls. The following procedures were performed: teleaudiometry screening with software that...

Background: Since in multiple sclerosis (MS), changes in speech and voice quality often precede other signs and symptoms; early diagnosis of these changes is necessary. In this study, an acoustic examination of phonation subsystem was performed. Due to the progressive nature of multiple sclerosis, the aim of this study was to examine the correlation between acoustic parameters ...

introduction:although several treatment approaches have been proposed for tinnitus, there are currently no food and drug administration (fda)-approved agents available to treat this condition. in this study, we evaluated the effect of gabapentin on the sensation of subjective tinnitus in patients with acoustic trauma referring to the ear, nose and throat (ent) clinic of taleghani hospital durin...

The existing economic necessity to increase production efficiency while reducing costs requires using all opportunities reduce the noise of equipment used in various industries, including road construction. At same time, requirements for low-noise should be applied both construction machines manufacturers and engines manufacturers. Numerous studies acoustic characteristics allow noting that lar...

Abstract Acoustic telemetry is widely used to investigate aquatic animal movement. Pulse position modulation (PPM) an acoustic method that allows multiple unique identification codes be transmitted at a single frequency, typically in the 69 kHz range. However, because potential number of (i.e. tags) ultimately limited by pulses PPM signal, this poses practical limitation. In addition, different...
