A and C weighting change the number, not the noise · review
The only meter here offering both A and C weighting, which is what separates a reading that follows human hearing from one that includes low-frequency energy.
What the figures leave us with The one to buy if the noise is low. Two weightings beat a tighter figure on one.
The only meter in this hub that can measure the same noise two legitimate ways.
A measuring range of 30 to 130 dB with a stated accuracy of ± 2.0 dB. A-weighted and C-weighted measurement, with the A-weighting described as simulating the frequency characteristic of human hearing at low intensity. Fast and slow response modes. A four-digit LCD with 0.1 dB resolution, backlit and described as large.
Point any two meters at the same noise with different weightings and they will disagree by a wide margin, and neither is faulty. A-weighting is the standard for judging how loud something seems; C-weighting keeps the low frequencies that A discards.
That difference is not a nuisance — it is diagnostic. A noise that reads 55 dBA and 78 dBC is almost entirely low-frequency, which tells you what is producing it and what kind of insulation would help. A meter with only A-weighting cannot make that comparison at all.
Indicative. A classified meter and a calibrator are what a measurement needs to be used for anything formal.

When the noise is low-frequency. A-weighting discounts bass heavily because human hearing does; that is right for judging annoyance from speech-range noise and wrong for a rumbling plant room or music through a party wall, where C-weighting shows what A-weighting hides.
No. They are different measurements of the same sound, and the difference between them is itself informative — a large A-to-C gap means the energy is at low frequency.
It is looser than the ± 1.5 dB of the cheaper meters here. On an indicative instrument used for comparisons, the weighting options matter more than half a decibel.

Low-frequency noise — plant, traffic, bass through a wall — that A-weighting under-reports.
Listed because the accessory names this instrument itself.
Amazon reports what buyers took in the month before this page was last checked: at least 500.
The figure is a floor, rounded by Amazon, and read through Keepa — it says what buyers picked, not what a maker claims.

30–130 dB · ± 1.5 dB · A and C weighting · 43,000-record logger · DC output
A logging meter storing up to 43,000 readings for export to a PC, with A and C weighting, a three-color LED warning and a DC output for external recording.
Best for: Establishing what a noise does over hours or days, which a handheld reading cannot show.
35–130 dB · MAX hold · large backlit display
A 35 to 130 dB handheld meter with a MAX function and a large backlit display. Its title carries the word "geeicht" — a manufacturer claim, reported here as one.
Best for: Household comparisons — before and after a change, one room against another.
30–130 dB · ± 1.5 dB at 94 dB / 1 kHz · A-weighted · fast and slow response
A 30 to 130 dB meter publishing its accuracy with the conditions it applies at — ± 1.5 dB at 94 dB and 1 kHz — with A-weighting and fast and slow response modes.
Best for: Getting a sense of a noise problem, with a figure whose conditions are stated.
