Sounds are produced by the vibrations of material objects‚ and travel as a result of momentum transfer when air molecules collide. Our subjective impression’ about the frequency of a sound is called pitch. High pitch has high vibration frequency‚ while low pitch has a low vibration frequency. A pure musical tone consists of a single pitch or frequency. However‚ most musical tones are "complex summations" of various pure frequencies - one characteristic frequency‚ called the fundamental‚ and

Beginning Vibration Analysis with Basic Fundamentals By: Jack Peters Beginning Vibration Introduction Understanding the basics and fundamentals of vibration analysis are very important in forming a solid background to analyze problems on rotating machinery. Switching between time and frequency is a common tool used for analysis. Because the frequency spectrum is derived from the data in the time domain‚ the relationship between time and frequency is very important. Units of acceleration‚ velocity

The purpose of this lab that was completed was to observe standing wave patterns in clamped strings‚ and understand the effect of the standing wave frequencies of changing the length (L)‚ tension (T)‚ and linear density (p) of the strings. Standing wave patterns in strings are observed at certain excitation frequencies for special values of L‚ T‚ and p. A standing wave can be defined as a vibration of a system in which some particular points remain fixed while others between them vibrate with the

High Frequency communication refers to radio communication in the range of frequency between 3-30 MHz or 3 000 000 – 30 000 000 Hz. The wave length range of High Frequency is 10-100 meters The Higher the frequency the shorter the wave length. High Frequency belongs to the radio portion of the electromagnetic spectrum. When electric current is sent back and forth through a wire an electromagnetic wave is created which can be amplified and transmitted out through an antena. It can then be received

Abstract The overall objective of this lab was to a digital oscilloscope to measure various signals. The goal of Part 1 was to measure the mean value‚ the frequency‚ peak to peak voltage‚ and the RMS voltage of a triangular input signal. To meet this goal‚ a function generator was used to generate a 1 kHz triangular wave signal with a 1 V amplitude‚ and the oscilloscope was used to measure the values of that signal. Using the oscilloscope‚ the mean value was found to be -37.6 mV‚ the RMS Voltage

Purpose: To investigate the relationship between the speed of sound in air through the pulse-echo experiment and the measured air temperature. Hypothesis: I believe the measured air temperature will affect the speed of sound because sound waves are longitudinal waves composed of the alternating compressions and rarefactions in air. If the air temperature is below 0°C‚ then the speed of sound would be lower than 331.6 m/s and if the air temperature is above 0°C‚ then the speed of sound would be higher
