Noise pollution is a major environmental problem in Kerala. It is caused by a variety of sources including motor vehicles, construction sites, industrial activities, and everyday activities like shouting, playing music, and using loudspeakers. The state has implemented several measures to reduce noise pollution, including setting noise limits for different areas, monitoring noise levels, and …
Uses of ultrasonic waves 1. Medical imaging: Ultrasonic waves are used in medical imaging to produce a visual representation of internal body structures. Ultrasound is used to detect fetal anomalies, diagnose diseases, and guide medical procedures. 2. Cleaning: Ultrasonic waves are used in industrial and commercial cleaning applications to remove dirt, rust, and scale from …

When earthquakes occur infrasonic waves are produced and animals respond to it. why ? Infrasonic waves are sound waves that have a frequency lower than the lower limit of human hearing, which is typically around 20 Hz. It is believed that animals can sense these low frequency sound waves better than humans because they have …
Limits of audibility The range of frequencies that humans can hear is generally considered to be between 20 Hz and 20,000 Hz. This range can vary slightly from person to person, but it is generally accepted that any sound outside of this range is considered inaudible. Ultrasonic sound and Infrasonic sound Ultrasonic sound is sound …
The ear is an organ responsible for hearing and the sense of balance. It contains a number of different components that work together to detect sound and convert it into electrical signals that are sent to the brain. The outer ear, or pinna, collects sound waves and directs them into the ear canal. The ear …
Communication The loss of hearing can cause difficulties in communication in a variety of ways. First, it can be difficult to understand what others are saying due to reduced sound clarity, which can lead to confusion and frustration. It can also be difficult to follow conversations in noisy environments, as well as to participate in …
Sound is a form of energy that is propagated through a medium such as air, water, or solid materials as a wave. It is created by the vibration of an object, which creates a pressure wave that travels through the medium. The speed of sound depends on the medium it is traveling through; for example, …
Pitch The pitch of a sound is a subjective measure of the frequency of the sound and is related to the perceived highness or lowness of the sound. The pitch of a sound is measured in hertz (Hz). Loudness Loudness is a measure of sound intensity, or the volume of a sound. It is measured …

The natural frequency of an object is determined by its mass and stiffness. Heavier objects tend to have lower natural frequencies, because they require more energy to vibrate, while lighter objects tend to have higher natural frequencies, because they require less energy to vibrate. Additionally, stiffer objects tend to have higher natural frequencies, because they …
A simple pendulum is a mass, or bob, suspended from a pivot point, such as a nail or a string, so that it is able to swing freely. When given an initial push, the mass swings back and forth in an arc, repeating the same motion over and over. A simple pendulum is used to …
