Rachlle Bou Serhal is one of those incredible people once you meet you can’t help but admire.  In her presentation to AEE students she reveals what she believes is the essence of a good leader in project based environments. She talks about the importance of hearing preservation as she is currently in-depth researching the topic as a Ph. D candidate at the Ecole de Technologie Superieure in Montreal. She showed how to look at Equal Loudness Contours  and how they relate to dBA wighting and that we don’t hear all frequencies at the same loudness level.  She referenced the Etymotic ER-20‘s as a great selection for the price and great protection for your ears.
