#HearingSafety: Put physical distance between you and loud noise when it is present. If possible, stand at an angle from the noise, not directly in front of it.

#SafetyTips: Wear ear protectors (earplugs or earmuffs) if you are using noisy equipment such as power drills, saws, sanders or lawn mowers.

#DidYouKnow? When the Eustachian tube fails to maintain pressure, resulting in dizziness, discomfort and ear pain etc.

So I'm a Speech Pathology major, and one of the classes I'm currently taking is Hearing Science.

This class involves an end of semester presentation, and I have chosen to do my research on the idea of Overtones, Natural Harmonics, and Difference Tones in music. I find it fascinating.

Most musicians have experienced this phenomenon at one point of another where you're singing or playing one note, but in addition to hearing that note, you hear a second note that corresponds to the note you played/sang, but isn't that note. Ever happen to you?

Point is, while I've been doing my research, I haven't been terribly successful in finding literature about this phenomenon in relation to hearing science (and I have a minimum number of resources that I haven't reached yet). So if anyone out there has any kind of literature that they'd be willing to share, or even just the name of an author or article that may be helpful, I'd be eternally grateful.

In addition, I'm interested in hearing about if any of you have experienced this phenomenon yourselves. Including any details you can remember about it (were you playing/singing at a particularly high pitch? What instrument was being used? If you continue to play, does it happen often?)

It's all for the sake of research and school so any and all help or suggestions - no matter how menial or small you may think it is - it would be immensely helpful to me.

You can send me a message on here, or if you'd rather explain via e-mail, message me here and I'll provide my e-mail address. Thanks in advance to anyone who can help me.

Anyone?
