Hearing protector data - SNR and HML
Finding even simple SNR or HML data on hearing protection can be a frustrating experience sometimes, and the more detailed APV data can be even harder to find. Some manufacturers, at best, make the APV data available for a single product at a time meaning flicking between them to compare them, or don't publish it on their websites at all but have at some point given it to retailers who display it there. This table will continue to develop to incorporate a wide range of the hearing protection available today making comparison data readily available to help people looking for a specific level of protection and will pull APV data in from other sources where the manufacturer isn't overly helpful.
Clicking on the headings will sort by that criteria, or use the 'filter' option to sort by price, type, function (e.g. detectable), etc.
- Price per pair is the equivalent price when bought in commonly-sold units, so individual or in packs depending on the plugs. Prices are as they were available and priced on the day they were added to the list. Prices are ex-VAT where the manufacturer or supplier prices ex-VAT. This is provided as a rough guide so readers know if they are looking at the region of a fiver for something or more like twenty-odd quid. If not available in the UK, some are still included as EU sellers are available and will sell to UK but priced in Euro - many Uvex products seem to be available in other parts of the EU only.
- SNR and HML hearing protector performance data has been obtained direct from the manufacturer. APV has been obtained from the manufacturer where they have made it available, otherwise I have referenced the alternative source in the 'source' column. If I have not found current APV data it will state 'na'. Care has been taken not to use American data. (Particularly looking at you Honeywell Howard Leight, we don't all use NRR in the parts of the world which are not America. Finding UK/EU data for Honeywell products is hard as the Howard Leight site defaults to Yankeeland info). The 63Hz APV is useful but not critical to hearing protection suitability assessments and some manufacturers do leave this figure off.
- Honeywell bought the makers of the Howard Leight range a few years ago. Here in the UK the branding has been changed over to 'Honeywell Howard Leight' or even just 'Honeywell' for some but the old Howard Leight is still used in many retailers. I have tried to tread a line between them and use the name the product is most commonly known as in the UK when referencing the manufacturer.
- For foam plugs, sometimes the manufacturer specifies disposable or reusable. For foam-only plugs, if no specification is given I have classed it as disposable.
- Where manufacturers have given pretty much no data at all other than the SNR, with no HML or APV, the recommendation is not to buy it. If they want your trade they should at least make all the data available for you to make the best-informed decision possible.
- All the data is owned by the manufacturers and gathered from what they have made publicly available. All the data is therefore in the public domain. However, this has taken a very long time to track it all down and collate and this presentation of it remains the property and copyright of The Noise Chap - no copying and pasting it all please.
