Power of Frequency Explained
Humans get constantly exposed to different sounds. Some of them are more pleasing than others. It's due, in part, to the frequency at which those sounds get generated. The power of frequency can exist in how it affects human emotions and how it can be used to heal or harm people. The power of frequency often gets underestimated. Frequencies can powerfully impact human emotions, thoughts, and overall well-being. They are instrumental in healing or harming individuals, depending on the frequency they get exposed to. Sound frequencies are perhaps the most common type of frequency. Sound waves are vibrations that travel through the air (or any other medium) and cause ears to vibrate, creating sound. The pitch of a sound gets determined by how fast the waves are vibrating. The higher the pitch, the faster the waves will vibrate. Sound frequencies can be used to heal or harm people.
Frequency Analysis of Vibration Energy Harvesting Systems
Frequency Analysis of Vibration Energy Harvesting Systems aims to present unique frequency response methods for analyzing and improving vibration energy harvesting systems. Vibration energy is usually converted into heat energy, which is transferred to and wasted in the environment. If this vibration energy can be converted into useful electric energy, both the performance and energy efficiency of machines, vehicles, and structures will be improved, and new opportunities will open up for powering electronic devices. To make use of ambient vibration energy, an effective analysis and design method is established and developed in this book. The book covers a wide range of frequency response analysis methods and includes details of a variety of real-life applications. MATLAB programming is introduced in the first two chapters and used in selected methods throughout the book. Using the methods studied, readers will learn how to analyze and optimize the efficiency of vibration energy systems. This book will be ideal for postgraduate students and researchers in mechanical and energy engineering. - Covers a variety of frequency response analysis methods, including Fourier and Laplace transform, transfer function, integration and state space for piezoelectric and electromagnetic vibration energy harvesting analysis - Provides coverage of new and traditional methods of analyzing and optimizing the power and efficiency of vibration energy harvesting systems, with MATLAB exercises provided throughout - Demonstrates a wide range of real-life applications, such as ocean wave energy conversion, vehicle suspension vibration energy harvesting, and more
