Equivalent threshold sound pressure levels (ETSPLs) for Oscilla H210A circumaural audiometric headphones

Objective: To determine ETSPLs for the Oscilla H210A circumaural audiometric headphones.Design: ETSPL measurements were performed for 11 audiometric frequencies with the ISO 8253-1 (2010) bracketing procedure.Study sample: The study was based on 25 otologically normal test subjects.Results: ETSPLs are provided for an ear simulator according to IEC 60318-1 (2009) along with a detailed measurement uncertainty budget.Conclusions: ETSPLs for the Oscilla H210A headphones may be used to update ISO 389-8 (2004), the reference ETSPL standard for circumaural audiometric headphones.
