Understanding Sound and Acoustics
Sound is a branch of Physics that is concerned with the study of the physical properties of mechanical waves that are audible or can be heard. Acoustics includes trhe study of sound frequencies that cannot be heard, such as ultrasound and infrasound.
Ultrasound consists of sound frequencies higher than the upper audible limit of human hearing, while infrasound consists of frequencies below what can be heard.
The knowledge of Physics is important for the development of the products we use. It is also an interesting and exciting subject of value in many walks of life. There is a great need for people who understand scientific principles and know how to think logically. Your knowledge and skills in these areas can help you excel in school, advance your career or improve your business.
The purpose of these free online lessons is to give you a start at improving your scientific knowledge of physics that will help you become a champion in the field. If you have any questions, send me an email.
