Of these 3, I can't hear the 17KHz.wav nor the mosquito_sound_wave_feature, but I can hear the 20060610_Ringtone. (See links in original message below.) Why? Because they differ in frequency.
The 17KHz.wav is indeed 17Khz. The mosquito_sound_wave is 16Khz. The 2006010_Ringtone is a mere 15Khz. Btw, I have screen captures that show these frequencies for each sound if anyone's interested. -- Sue Frantz Highline Community College Psychology Des Moines, WA 206.878.3710 x3404 [EMAIL PROTECTED] http://flightline.highline.edu/sfrantz/ -- Office of Teaching Resources in Psychology Assistant Director, Project Syllabus http://www.lemoyne.edu/OTRP/projectsyllabus.html -----Original Message----- From: FRANTZ, SUE [mailto:[EMAIL PROTECTED] Sent: Thu 10/19/2006 12:13 PM To: Teaching in the Psychological Sciences (TIPS) Subject: [tips] Re: Hearing ringtones (was:: 18-20 kHz and its marketability) Here's a wav file: http://www.jetcityorange.com/toys/17KHz.wav And here's an MP3 version from the NY Times: http://graphics.nytimes.com/packages/audio/nyregion/20060610_RINGTONE.mp 3 <http://www.bbc.co.uk/wiltshire/content/articles/2006/04/04/mosquito_sou nd_wave_feature.shtml> -- Sue Frantz Highline Community College Psychology Des Moines, WA 206.878.3710 x3404 [EMAIL PROTECTED] http://flightline.highline.edu/sfrantz/ -- Office of Teaching Resources in Psychology Assistant Director, Project Syllabus http://www.lemoyne.edu/OTRP/projectsyllabus.html
