Test of headphones

Join webinar

Live webinar organised by Sound Hub Denmark
International Noise Awareness Day

Conduct and learn from objective and subjective tests to avoid hearing damage of headphone users and to reduce noise

Join us for a live webinar, when we put focus on the importance of proper tests of headphones in the development phase.

Together with our partners GRAS Sound & Vibration, FORCE Technology and GOmeasure we would like to raise awareness of the harmful effects of noise caused by headphones on hearing, health and quality of life, unless time is spend on necessary tests. Recommendations will be given to test equipment and setups followed by practical examples.

More than ever before, we spend hours wearing headphones e.g. for music, phone calls, gaming, podcasts, e-books, movies etc. – or even just to remove noise from surroundings – hence the need for proper tests.

The event is a part of the International Noise Awareness Day initiative raising awareness of noise impact on the welfare and health of people. This year we at Sound Hub Denmark put focus on how professionals and the right equipment can minimise impact and annoyance.

Hearing damage caused by headphones? 
Get introduced to the recommended test equipment for testing according to the EN50332 standard. To avoid hearing damage for users the SPL value measured in the ear canal may not exceed more than 94 dB according to EN50332 standard.

Decibel Noise
Annoyed by sound leakage from headphones?  
Insulation noise leakage might be very distracting to the surroundings of headphones users, if leakage performance is poor and the listening volume is high. Therefore, it is recommended to measure and test the insulation value.

Leakage Noise
How is noise perceived in and from headphones?  
Active noise cancellation is one of the key features in many headphones. How do we subjectively describe noise and how to measure such professionally to deliver a headphone experience living up to the expectation of users? Learn from for example listening panels.
