The Signals and Noise: Learning to Tune In
There’s a concept in engineering called signal-to-noise ratio. It describes how much meaningful information — the signal — comes through relative to the unwanted interference — the noise. In telecommunications, a low signal-to-noise ratio means a garbled transmission. In life, it means something far more costly: a distorted sense of what actually matters.
I spent years in engineering learning about filtering noise. You calibrate instruments, you isolate variables, you eliminate interference so the truth of a system can reveal itself clearly. It’s methodical. Scientific. Precise.
Then I moved into management — and everything I thought I knew about filtering got tested in ways no circuit ever could.
As a regional manager in customs brokerage, the volume of incoming “information” on any given day is staggering. Emails, escalations, regulatory updates, team dependencies, client expectations, cross-border complexities. And layered beneath all of that: meetings. So many meetings. Some necessary. Some not so much. Each one pulling my attention away from the deeper work of thinking, deciding, and leading well.
The noise in my professional world isn’t always obvious. It doesn’t always announce itself as a distraction. Sometimes it arrives dressed as urgency. A ping. A cc’d email thread that spirals into twelve replies. Meetings that could have been a two-line message. The noise is loud, relentless, and — if you’re not careful — it starts to feel like the signal.
But it isn’t.
The same is true in life outside the office. Social media is a masterclass in noise. Feeds engineered to keep you scrolling, opinions optimized to provoke reaction, curated lives designed to make you question your own. I’ve caught myself measuring my progress against the highlight reels of others — people whose context, timeline, and definition of success are entirely different from mine.
And then there’s the weight of other people’s expectations. The quiet pressure of being the person others depend on — at work, at home, in the spaces in between. Dependence can be an honor. It means people trust you. But unchecked, it becomes its own kind of noise: a constant hum of others’ needs that drowns out your own voice, your own direction, your own signal.
The question I’ve had to sit with — and still sit with — is this: What is my signal?
Not what is loudest. Not what is most urgent. Not what other people expect me to chase. But what is actually true, meaningful, and worth orienting my energy toward?
For me, the signal sounds like clarity of purpose. It sounds like the satisfaction of a complex problem solved well, a team developed with intention, a decision made from principle rather than pressure. It’s quieter than the noise. It always is.
That’s the paradox. The things that matter most rarely shout. They wait — patiently, steadily — on the other side of the static.
Engineering taught me that you can’t eliminate noise entirely. You can only manage your relationship with it. You build systems that recognize it for what it is, reduce its influence, and amplify what’s real.
I think that’s the work of a reflective life, too. Not the pursuit of perfect silence — that doesn’t exist — but the practice of tuning. Returning, again and again, to the signal. Asking the harder question beneath the easier one. Choosing depth over volume.
The noise will always be there. The meeting requests won’t stop. The notifications will keep coming. People will keep needing things.
But so will the signal — quiet, persistent, and entirely worth listening for.
