Hearing protection data

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.

As this has frustrated me over the years I've finally got my act together and done some thing about it, pulling this data together into one single place making comparisons of hearing protection easy, and providing a simple data source  to help people looking for a specific level of protection.

Some tips 

  • This has to be viewed on a laptop or desktop as the database cannot load on mobile devices, sorry.
  • For reasons I cannot fathom, sometimes the data says 'loading'  - just hit the refresh button in your browser and it will be fine.
  • Clicking on the headings will sort by that criteria, or use the 'filter' option to sort by price, type, function (e.g. detectable), etc.
  • For E-A-R search for 3M (the manufacturer) as the search function doesn't like the hyphens in the E-A-R name.
  • 'Protector Basics' has SNR, HML, cost and style info, 'Protector APV' has the more detailed APV (octave band) data.
  • If you are in the food industry then searching for 'detectable' will bring up all detectable plugs, same if you want protectors with things like MP3 connections.
  1. 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 Euros - many Uvex products seem to be available in other parts of the EU and sell into the UK from there.
  2. SNR, HML and APV performance data has been obtained direct from the manufacturer wherever possible but if it has not been available and I used another source this is noted in the 'data source' column. If APV is blank I couldn't find any and would recommend you don't use them - if they can't be bothered to get it right then they don't deserve your business. 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 in Americaland, of which there are many. Finding UK/EU data for Honeywell products is a nightmare as the Howard Leight site constantly defaults to Yankee info). While I think of it, the 63Hz APV value is useful but not critical to hearing protection suitability assessments and some manufacturers do leave this figure off so if it's missing then that's why.
  3. 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.  
  4. 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.
  5. 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.
