The article focuses on formulas for calculating the addition of sound levels when the disturbances of the acoustic pressures that determine them are correlated. Based on the numerical experiments, determine the level of possible errors for different coherence conditions of two noise sources. The performed analyses are associated with the classical calculus of algebra of decibel numbers, as well as its modifications securing the required correctness of its axiomatic. Presents the desirability of its use in the problems of developing measurement data of small values of sound levels. Relates the need for their potential applications to computational issues relating to the study of the sound field in special rooms (e.g., radio and television studios, anechoic chambers, lave caves) and the study of the environment in which these devices or objects are located. Draws attention to their importance in estimating type B uncertainty in controlling the state of acoustic hazards in the environment. [ABSTRACT FROM AUTHOR]

This study focuses on freedom of expression among university radio stations in Turkey. Our aim is to reveal the obstacles university radio stations face in speaking freely and to propose a solution to them. We take our conceptual framework from the Habermasian public sphere and focus on the practice of speaking on the radio. Using a qualitative analysis method, we conducted in-depth interviews with the managers of 34 university radio stations in 21 different cities in Turkey. We found that there are many obstacles to freedom of speech facing university radio stations in Turkey. [ABSTRACT FROM AUTHOR]

The nonprofit radio sector in Canada includes over 180 community and Indigenous stations. Studies of nonprofit radio programming note the diversity of on-air content from news to music, which is in line with the sector's mandate. However, does the assortment of content translate into a diversity of individuals behind the microphone? And who is making decisions in station management and governance?. To better understand the equity practices found within nonprofit radio, this article highlights the results of an online survey to quantify the diversity found among the board members, volunteers, and employees who operate these stations.
