Author: Haoyang Chen Date: 2/23/2013 Experiment No.: 2 Title: Synthesis - A Square Wave‚ a Musical Note and Sound Cancellation Introduction: In this experiment‚ we will do three parts to find out the synthesis sound. They are a Square Wave‚ a Musical Note and Sound Cancellation. For the first part‚ it is the superposition of sine wave. We are going to construct a square wave (approximately) by adding together some pure tones of different frequencies. This stretched string vibrating at

What are UltraSonic Waves? Ultrasonic waves are sound waves with frequencies high about human hearing and short wave lengths. Sound waves have frequencies about 20‚000 to 100‚000. Also Ultrasound frequencies range from 20 kHz (the upper range of hearing for a young adult human) through 150 kHz (audible to some bats and other creatures)‚ right up to 10 MHz (used in some medical treatments and industrial cleaning applications). While these frequencies overlap with those of radio waves‚ they are different

Weird Animals Lesser water boatman ( Micronecta scholtzi): The loudest penis on Earth The lesser water boatman‚ just 2 millimetres long‚ is the loudest animal on Earth and more impressive fact is that he makes its noises using its penis instead of its mouth or legs or wings. James Windmill‚ engineering expert‚ in mid-2011 from the Centre for Ultrasonic Engineering at the University of Strathclyde (Scotland) reported in PLoS One that the lesser water boatman can produce sounds
