To my ear, I was certain I was hearing some strong, distinct partials. Tunelab shows the one large spike slowly increasing, accompanied by at least nine visible partials. At the lower end, the partials are certainly more distinctly heard than the fundamental, despite their volume being so much lower. The partials are mathematically placed but are not based on multiples of 2, 3, 4, etc as we are accustomed to with musical tones.  <DIV><BR></DIV> <DIV>See attached screenshot, taken when the tone is at 60hz.</DIV> <DIV><BR></DIV> <DIV>Jason <BR><BR> <DIV class=gmail_quote>On Tue, Mar 15, 2011 at 9:12 AM, Rob & Helen Goodale <SPAN dir=ltr><<A href="mailto:rrg@unlv.nevada.edu">rrg@unlv.nevada.edu</A>></SPAN> wrote:<BR> <BLOCKQUOTE class=gmail_quote style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid"> <DIV style="PADDING-RIGHT: 10px; PADDING-LEFT: 10px; PADDING-TOP: 15px" name="Compose message area"> <DIV><FONT face=Calibri>Here's an important question for piano technicians - How good is your hearing?</FONT></DIV> <DIV><FONT face=Calibri></FONT> </DIV> <DIV><FONT face=Calibri>There is an interesting and fun on-line test you can take.  It won't test levels but it will give you an idea of your hearing range.</FONT></DIV> <DIV><FONT face=Calibri>Keep in mind that results may vary depending on the frequency response of your computer's speakers.</FONT></DIV> <DIV><FONT face=Calibri></FONT> </DIV> <DIV><FONT face=Calibri><A title="http://www.youtube.com/watch?v=4G60hM1W_mk
