The phrase "a frequency of around" is correct and usable in written English.
It can be used when discussing approximate measurements or values related to frequency in various contexts, such as science, music, or telecommunications.
Example: "The radio station broadcasts at a frequency of around 101.5 MHz."
Alternatives: "an approximate frequency of" or "a frequency close to".
The song was a repetition of single notes, with a frequency of around 6.4 kilohertz.
A self-sustained flow oscillation at a frequency of around 1 kHz is found numerically, in good agreement with the unsteady wall pressure measurements.
In an AM (amplitude-modulation) radio broadcast, electromagnetic waves with a frequency of around one million hertz are generated by currents of the same frequency flowing back and forth in the antenna of the station.
This energy tends to dissipate rapidly, but when SAWs reach a frequency of around 10MHz in water-based fluids, they give rise to an unusual phenomenon called acoustic streaming.
The appearance of a periodic bottleneck in the solver performance is also reported, believed to be hardware related; spikes in iteration-time occur with a frequency of around 11 Hz for both GPUs, independent of the size of the problem.
The pulse length that we used was 20 ns at a power of 3 × 107 W with a frequency of around 10 Hz.
MGUS is common in the elderly but only a minority of MGUS individuals progress to develop symptomatic MM, with a frequency of progression of around 1% per year.
Patients thus seem to optimise the health gain incurred by more frequent and burdensome endoscopic surveillance, up to a frequency of testing of around once a year.
For most of the work's duration, twenty-four subwoofers, placed with their cones pointed upward, emit electronic tones that vibrate at a frequency of 10.67 hertz, or around ten oscillations per second.
Heterozygous transgenic Int6sh female FVB/N mice developed tumors at a frequency of 41.7% (10/24) around 18 months of age after giving birth to several (2 4) litters (Table 1).
The composite material has a permeability of 8.46, a loss tangent value of 0.1 at a frequency of 30 MHz and saturates around 0.13 Tesla.
