In audiovisual contexts, different conventions determine the level at which background music is mixed into the final program, and sometimes, the mix renders the music to be practically or totally inaudible. From a perceptual point of view, the audibility of music is subject to auditory masking by other aural stimuli such as voice or additional sounds (e.g., applause, laughter, horns), and is also influenced by the visual content that accompanies the soundtrack, and by attentional and motivational factors. This situation is relevant to the music industry because, according to some copyright regulations, the non-audible background music must not generate any distribution rights, and the marginally audible background music must generate half of the standard value of audible music. In this study, we conduct two psychoacoustic experiments to identify several factors that influence background music perception, and their contribution to its variable audibility. Our experiments are based on auditory detection and chronometric tasks involving keyboard interactions with original TV content. From the collected data, we estimated a sound-to-music ratio range to define the audibility threshold limits of the class. In addition, results show that perception is affected by loudness level, listening condition, music sensitivity, and type of television content.

Background: CPAP has been shown to be particularly beneficial in the management of acute cardiogenic pulmonary edema by reducing both preload and afterload, thus decreasing the work of breathing and improving oxygenation.
Methods: This study was a prospective observational study, conducted in the period from 2022 to 2024, assessing the effectiveness and safety of prehospital CPAP therapy use in patients with acute cardiogenic pulmonary edema, administered alongside standard care.
Results: In this study, 50 patients with acute cardiogenic pulmonary edema were treated by physician-led emergency teams in the Canton of Sarajevo.

Background: This study investigated whether a sound intervention tuned to 432 Hz (Hz) yields differential effects on cardiovascular parameters and psychological outcomes compared to 443 Hz, which is the concert pitch in German professional orchestras.
Methods: Using a randomized cross-over design, patients with cancer were recruited to receive both a 15-minute sound intervention with a body monochord tuned to 432-443 Hz. Before (pre) and after (post) intervention, cardiovascular parameters were measured using the VascAssist2.

Background: The effects of nurses' attitudes toward complementary and alternative medicine (CAM) in pain management in terms of safety and quality of life are important. Nurses turn to a CAM approach to deal with pain problems.
Aim: This study aimed to investigate nurses' attitudes toward CAM and to determine their sociodemographic and pain-related characteristics.

Anxiety, pain and poor well-being are major issues in elderly individuals. Complementary interventions, such as music and hypnosis, are increasingly used to address these issues. The objectives of this study were to assess immediate changes in anxiety, pain and well-being during personalized prerecorded music and hypnosis interventions compared to control sessions, and to explore participants' subjective experiences.

Background: There is a significant need for an effective and convenient symptom management and healing program for people experiencing post-traumatic stress disorder (PTSD) symptoms; however, research on this topic is lacking.
Objective: This study explored the experiences of individuals with PTSD who used a mobile traumatic stress management app with neurofeedback-based meditation and binaural beat music to promote their psychological recovery.
Methods: This study used a qualitative research method to explore the experiences of neurofeedback-based meditation and binaural beat music using a mobile traumatic stress management app to promote the psychological recovery of people experiencing chronic traumatic stress.
