dc.description.abstract It is estimated that approximately 360 Million people have a permanent disabling hearing loss (WHO, 2015). The majority of these people live in lower to middle income countries, where screening and follow-up treatment is not always accessible (WHO, 2015). School based hearing screening is one of the procedures that are not always available due to a number of challenges one of which include the high cost of audiometrical headphones. School based hearing screening is performed with an audiometrical headphones and audiometer, it usually can be used to test all school-aged children and adults. In an attempt to reduce the cost of school based hearing screening, this study evaluated the Sennheiser HD 202 II headphone to establish it as a widely available and cost-effective alternative for audiometrical headphones currently used. The headphones were compared to ISO standards (ISO 389-1, ISO 389-5 and ISO 389-9) and IEC standards (IEC 60318-1 and IEC 60645-1). The following characteristics of the headphone were compared: equivalent threshold sound pressure levels, attenuation, maximum permissible ambient noise levels, force of the headband, total harmonic distortion and frequency response. After evaluation the Sennheiser HD 202 II does not show the same standard as audiometrical headphones for diagnostic testing. The headphone can however be used for screening purposes if a few measures are taken into account. The correct ETSPL values should be used, disruptive background noise should be avoided and only the frequencies from the research (250- 1600 Hz) can be tested. once these measures are taken into account the Sennheiser HD 202 II proves to be a cost-effective alternative headphone for screening purposes. en_ZA
