Definition
Noun: * Sound Reflection: The phenomenon where a sound wave encounters a surface or boundary and is sent back into the medium from which it came, resulting in a repetition of the sound. This is the core physical process.
Usage
The term "sound reflection" is a technical noun used to describe the physical process itself. It is commonly used in scientific, acoustic, and engineering contexts. * The design of the concert hall minimizes unwanted sound reflection from the walls. * Engineers studied the sound reflection properties of different materials. * The sound reflection from the canyon wall created a distinct echo.
Advanced Usage
- "Principle of sound reflection": A fundamental concept in acoustics stating that the angle at which a sound wave strikes a surface equals the angle at which it is reflected.
- The sonar system operates on the principle of sound reflection.
Variants and Related Words
- Reflection (n): The more general term for the throwing back of a wave (light, sound, heat) by a surface.
- Echo (n): A distinct, audible repetition of a sound caused by sound reflection from a surface. An echo is a specific perceptual result of the physical process of sound reflection.
- The echo in the mountains is a clear example of sound reflection.
- Reverberation (n): The persistence of sound in a space as a result of multiple sound reflections from surfaces. It is a series of rapidly decaying echoes.
- Acoustic Reflection (n): A synonym often used in technical fields.
Synonyms
- Acoustic reflection
- Audio reflection (less common)
Related Phrases
- Angle of reflection: The angle between a reflected wave and the normal (an imaginary line perpendicular) to the reflecting surface.
- Reflective surface: A surface that causes significant sound reflection.
Noun
- the repetition of a sound resulting from reflection of the sound waves
- she could hear echoes of her own footsteps
