Impact Vibration Frequency, Explained
Two clubs can deliver the same amount of "shock" and still feel completely different in your hands. Frequency is usually why.
When a clubhead strikes a golf ball, the collision sends a shockwave up the shaft that arrives at the grip as a rapid oscillation — not a single smooth push. Golfers usually describe this as "sting," "buzz," or a sharp jolt, but those words are really describing two separate physical properties: how much energy arrives, and how quickly it oscillates once it does. The second property, frequency, is the one most fitting conversations skip entirely.
Amplitude and Frequency Are Not the Same Thing
Amplitude is roughly what most people mean by "shock" — the overall size of the vibration. Frequency describes how fast that vibration oscillates back and forth once it starts. A low-mass, stiff clubhead paired with a stiff shaft tends to produce a high-frequency, sharp-edged vibration that reads as "sting" even at moderate amplitude. A higher-mass head with a more flexible, damped shaft can produce a lower-frequency vibration that feels like a duller thud even when the total energy transferred is similar.
For golfers managing joint sensitivity, high-frequency vibration tends to be the more aggravating of the two, since sharp, rapid oscillation is what tendons and joint capsules typically respond to with inflammation over repeated exposure.
Why This Matters More for Some Golfers Than Others
A golfer with no joint history might not notice much difference between a high-frequency and low-frequency miss — both just feel like "a bad one." For a golfer managing tennis elbow, arthritis, or a healing wrist, though, the frequency profile of repeated shots can be the difference between a comfortable practice session and a sore week afterward.
Two clubs can transfer nearly identical total energy on a mishit and still produce very different discomfort, because one delivers it as a sharp high-frequency spike and the other as a softer, slower wave.
How We Read Frequency During a Fitting
Our grip-mounted sensor captures the full vibration signature of each swing, not just a single "shock score." During a fitting, we look at how quickly a demo club's vibration signature decays and how sharp the initial spike reads, then compare that against your own reported comfort rating for the same swing. Clubs that measure similarly on amplitude can rank very differently once frequency and decay rate are factored in.
What Changes the Frequency Profile
Shaft material and internal construction have the largest influence — multi-material and dampened shafts are specifically designed to slow decay time and round off the initial spike. Grip compound plays a secondary role, cushioning the frequency that reaches your hand even when the shaft itself hasn't changed. Head design matters too: higher-MOI heads resist the twisting that often accompanies the sharpest, highest-frequency spikes on off-center strikes.
The Takeaway
If a club has ever felt like it "stings" more than another despite similar distance numbers, frequency is very likely the reason. It's a variable most standard fittings never measure, which is why we build a vibration reading into every session rather than treating comfort as an afterthought.
