: The study was approved by the Institutional Review Board, Tekniker Ethics Committee (IRB202200002). The board reviewed that the design of the user study met ethical requirements, following guidance from the European Commission on Ethics and Social Science and Humanities. The board’s assessment focused on protecting participant wellbeing, ensuring informed consent, protecting personal data, and maintaining transparency throughout the research process. The study’s design was evaluated for potential ethical implications, with measures implemented to mitigate any identified risks. Additionally, the use of HoloLens devices in the study was inspected to ensure compliance with safety standards. The HoloLens speakers, which can produce sound levels up to 85 decibels (dB), were deemed safe for extended use without risking hearing damage, aligning with the Noise at Work Directive (Directive 2003/10/EC).This directive sets the upper exposure action value at 85 dB for daily or weekly exposure levels, ensuring the safety of participants in accordance with European noise exposure regulations. The commitment to ethical integrity underscores the study’s dedication to responsible and respectful research practices.
