noise suppressor
C1technical
Definition
Meaning
A device or system that reduces or eliminates unwanted background sounds.
Any system, software, algorithm, or device designed to diminish or remove undesirable auditory interference, often while preserving desired signals; can refer to physical hardware, software processing, or integrated circuit technology.
Linguistics
Semantic Notes
Primarily technical term; often part of a compound noun phrase (e.g., 'active noise suppressor'). Implies active reduction rather than passive blocking.
Dialectal Variation
British vs American Usage
Differences
Identical term used in both varieties. Occasionally 'noise canceller' or 'noise cancellation system' may be preferred in marketing contexts in the US.
Connotations
In British technical contexts, may slightly favour 'noise reduction system'. No significant connotative difference.
Frequency
Slightly more frequent in American English due to larger consumer electronics market.

Usage
Context Usage
Business
Referring to features in headphones, microphones, or conferencing systems that improve communication clarity.
Academic
In engineering, signal processing, or acoustics papers discussing algorithms or hardware for noise reduction.
Everyday
When discussing features of headphones, car audio systems, or recording equipment.
Technical
Precise term in audio engineering, electronics, telecommunications, and acoustics for devices employing active or digital signal processing to reduce noise.
Examples
By Part of Speech
verb

Examples
By CEFR Level
- My new headphones have a noise suppressor.
- The noise suppressor makes calls clearer.
- You should turn on the noise suppressor when recording in a noisy room.
- This camera has a built-in noise suppressor for its microphone.
- The audio engineer applied a digital noise suppressor to remove the hum from the old recording.

Mnemonic
Think of a SUPPRESSor as something that PRESSes DOWN on NOISE, pushing it away.
Conceptual Metaphor
NOISE IS AN UNWANTED INVADER (suppressed, filtered, cancelled).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'шумный супрессор' – use 'подавитель шума' or 'шумоподавитель'.
- Do not confuse with 'глушитель' (silencer/muffler for vehicles).
- 'Noise suppressor' is a specific device, not general 'защита от шума'.
Common Mistakes
- Using 'noise suppression' as a countable noun (*'I have two noise suppressions') instead of 'noise suppressors'.
- Confusing 'suppressor' with 'compressor' in audio contexts.
- Misspelling as 'noise supressor' (single 'p').

FAQ
Frequently Asked Questions
A noise suppressor actively reduces continuous background noise (like hum or hiss) across the signal. A noise gate is a switch that mutes the signal entirely when it falls below a certain volume threshold, used to cut out short bursts of noise between wanted sounds.
They are very similar and often used interchangeably in marketing. Technically, 'noise cancellation' often implies active generation of an inverse sound wave (anti-noise), particularly in headphones. 'Noise suppression' can be a broader term encompassing both active and passive (filtering) methods.
Yes, by analogy. In electronics and signal processing, it can refer to circuits that suppress electrical noise. In image/video processing, 'noise suppressor' can refer to algorithms that reduce visual grain or static.
'Suppressor' is the standard spelling in both British and American English for this technical term, though '-er' is an accepted variant in general usage.
