Soundscapes
Soundscapes encompass the acoustic environment as perceived by humans, in context, which includes natural, human, and machine sounds.
Acoustic Fingerprinting
The process of analyzing and characterizing the unique set of attributes or elements that make up the sound of a particular environment.
Echo
The reflection of sound waves from a surface back to the listener, which can be a factor in environmental acoustics that influences sound clarity.
Acoustic Ecology
A field of study that examines the relationship, mediated through sound, between human beings and their environment.
Decibel (dB)
A logarithmic unit used to measure sound pressure level, commonly used in the context of environmental acoustics to quantify noise levels.
Traffic Noise Modeling
The use of computer algorithms to predict traffic noise levels for environmental assessment and urban planning decisions.
Noise Barriers
Physical constructions placed between noise sources and receivers to mitigate the adverse effects of noise pollution on people.
Underwater Noise Pollution
Noise generated by human activities that disrupts the marine environment, affecting communication, navigation, and survival of marine life.
Environmental Impact of Aviation Noise
The effect of noise created by aircraft engines and operations, which can cause community annoyance and disrupt wildlife.
Reverberation Time
The time it takes for the sound to decay by 60 dB in a closed space, affecting the acoustic quality and intelligibility of speech and music.
Wind Farm Noise
Noise created by the mechanical and aerodynamic processes of wind turbines, which can be a concern for local residents and wildlife.
Acoustic Comfort in Urban Planning
Consideration of the impact of sound and noise in the design and development of urban areas to ensure a comfortable soundscape.
Occupational Noise Exposure
Noise exposure that occurs in the workplace, which can lead to hearing impairment and other health issues for workers.
Psychoacoustics in Environmental Noise
The study of the psychological and physiological responses to sound, including environmental noises like traffic or construction.
Sound Insulation
The process of making a space resistant to the passage of sound waves, to reduce noise pollution especially in building design.
Soundscape Conservation
Efforts to protect and maintain acoustic environments, especially those with cultural or natural significance, from excessive noise pollution.
Hearing Loss Due to Noise Exposure
Occurs when the inner ear or auditory neural system is damaged by exposure to high sound pressure levels, often from noise pollution.
Noise Pollution
Refers to harmful or annoying levels of noise, such as that from vehicles or industrial machinery. It can have negative impacts on human health and wildlife.
