Noise: Why Your Message Isn’t Landing at Work
Whenever we communicate, noise gets in the way. Understanding the different types of noise — and how they distort meaning — is one of the most important communication skills managers can develop.
Noise: Why Your Message Isn't Landing at Work
Whenever we communicate, we are affected by noise.
In communication theory, noise refers to anything that interferes with a message — how it's sent, how it's received, and how it's understood. Noise is everywhere. Especially at work.
The more we understand it, the better chance we have of cutting through it, landing our message, and achieving our purpose with the people we're communicating with.
Editor's note — where this sits
This essay explores noise in communication — the interference that prevents messages from landing clearly. It draws on communication theory and years of teaching this model to managers and leaders. It sits in the Wiring layer of the Idea to Value system — the layer where meaning moves between people, and where most organisational friction quietly begins.
The Idea to Value system — five layers
Communication isn't as simple as it looks
It's tempting to think communication is straightforward.
You have an idea. You share it. Someone receives it. Job done.
Except that's rarely how it works. The sender has to encode an idea clearly. The receiver has to decode it accurately. The medium has to support the message. And at every stage, noise can interfere.
This explains why messages fail, why people misunderstand each other, and why "I've already explained this" is one of the most common phrases in organisations.
Where noise appears
One of the simplest ways to understand this comes from the Shannon and Weaver model of communication.
— It starts with a source — you. You have a purpose: an idea, a request, a story, a decision.
— You encode that purpose into a message.
— That message travels via a channel — conversation, email, video call, presentation.
— The audience decodes it and decides what it means — and what to do next.
Noise is anything that interferes at any point in that chain.
Four types of noise
Over time I've found it useful to group noise into four categories. This is the model I teach managers and leaders.
01
Physiological
Physical state
The sender's or receiver's physical and mental condition — fatigue, stress, hearing, energy levels.
e.g. Tired in a long meeting. Stressed during a difficult conversation.
02
Physical
Environmental barriers
External interference — inbox overload, notification noise, poor audio, distracting environments.
e.g. Email buried in a full inbox. Camera off in a video call.
03
Psychological
Mindset & emotion
Emotions, assumptions, power dynamics, and confidence — the most overlooked form of interference.
e.g. Anxiety before a senior meeting. Boredom in a long briefing.
04
Semantic
Meaning & language
Words interpreted differently than intended — jargon, ambiguity, technical language, cultural gaps.
e.g. Acronyms that exclude. Vague instructions that create assumptions.

The responsibility of the communicator
Yes, communication is a shared act. The listener has a role to play.
But responsibility sits primarily with the sender. It's on us to choose the right medium, reduce unnecessary noise, adapt our language, consider timing and context, and be in a fit state to communicate — and to help others be in a fit state to receive.
Good communication takes effort. It takes practice. And it takes awareness.
A useful reflection
When a message doesn't land, ask:
Was noise at play — and which kind? Could I simplify the message, change the medium, or shift the environment? Was the timing wrong? Was the audience too large?
Understanding noise won't eliminate communication problems. But it will dramatically improve your chances of being understood.
And in work, that makes all the difference.
