Corrections

If a figure, price, spec or quote on a guide is wrong, say which guide and which product, and link the maker's page or document you read. We check it against the maker's own publication, fix the guide and note the change on it.

Makers and brands

If you make one of the products we cover and your published noise figure has changed, send the spec sheet, manual or product page that shows the new figure and the condition it was measured under. We rank only on what makers publish, so a document is what moves a product. No brand pays for a place in a guide, and we do not take payment to add, move or remove one.

Readers

Questions about a product type we have not covered, or a figure you cannot find, are welcome. We cannot measure products for you, and we do not give medical or safety advice beyond what a maker's manual or a regulator says.
