Background and Aim: With regard to the shortage of proper materials in Persian for the evaluation of speech perception in children, this study aimed to develop the Persian version of the BKB sentence test, and determine its content validity in normal Persian speaking children aged 6-12 years. Methods: This study was an applied research. The study procedure comprised sentence construction, deter...

Background: Today, open-plan offices are among the most common work environments. Although the noise in these environments is usually below the standard level, it is one of the critical annoyance factors due to the nature of the mental work. Accordingly, this study aimed to assess noise effects on employee comfort and validate the Persian version of the assessment of noise effects on employee c...

measurement and analysis of noise level in various frequency bands was carried out in a textile factory. it was shown that the noise level in various working places, particularly in the weaving workshop, was quite excessive comparing to the standards and so, it may very likely result in producing hearing loss in the workers. to determine the hearing loss of the workers due to excessive noise, 1...

background: acoustic noise is one of the universal pollutants of modern society. although the high level of noise adverse effects on human hearing has been known for many years, non-auditory effects of noise such as effects on cognition, learning, memory and reading, especially on children, have been less considered. factors which have negative impact on these features can also have a negative ...

Substrate noise generated by digital circuits on mixed-signal ICs can disturb the sensitiveanalog/RF circuits, such as Low Noise Amplifier (LNA), sharing the same substrate. This paperinvestigates the adverse impact of the substrate noise on a high frequency cascode LNA laid out on alightly doped substrate. By studying the major noise coupling mechanisms, a new and efficientmodeling method is p...
