Review: Pulsar Nova model 45 noise meter and analyzer software

The Pulsar Nova Model 45 noise meter is really a combination of two distinct parts, the physical noise meter and the AnalyzerPlus software used to manage and review the results, both of which work together to make the whole product. One of them pretty useless without the other so to determine how the meter performs, the software has to be looked at as well. Which is a shame as aside from some design niggles, the physical meter seems pretty good, while the software, well, let's charitably say 'it'll be nice when they finish it'. Here is a full review of both the meter and the software based on a couple of months’ of regular use.

Best ways for bursting an ear drum

An ear drum, or 'tympanic membrane' for those who like proper words, is the thin partition between the outer ear and the middle ear, sealing off the ear canal and is the bit which vibrates in response to sound waves hitting it and turns noise into something you can hear. Bursting or puncturing it is fairly common, if painful, and after many years of doing hearing tests around the country, these are some of the most cringe-worthy stories I have been told about how people burst their own ears...

High noise for company drivers

This is an area which I have avoided tackling head-on in the past and generally turned a blind eye to it as it is an area packed with uncertainty and potentially large issues to sort out, but nevertheless it is an interesting question - how do the Noise Regulations apply to people driving a vehicle on company business? This would cover the obvious such as truck or van drivers, but also motorcycle couriers, anyone driving a company car on a work-related journey, or indeed anyone driving their own car on a work-related journey.

Most powerful hearing protector

Sometimes in a high noise area nothing beats the good old fashioned approach of 'most powerful is best' when it comes to hearing protection. But cost is not synonymous with best or most powerful.   

Out of the 170+ types of hearing protector listed on the Hearing Protection Data page on this site, these are the top ones ranked by SNR, the single number which is an indicator of how powerful they are at reducing noise.

Review: Flare Audio ISOLATE ear plug marketing

In the ISOLATE, Flare Audio have come up with an ear plug that is certainly very different to the standard types on offer by the major manufacturers, and accompany them by some very slick marketing. The ISOLATE and ISOLATE Pro plugs have pricing to match the marketing though, at £25 and £50 per pair respectively, but is the marking anything other than sales fluff? As someone who has spent the best part of two decades working in the noise safety area, and who has conducted many thousands of hearing tests on people, here are a few of their claims and statements examined more closely to see how true or accurate they are.

Bone Conduction Headphones

Social Media these days seems to be full of companies launching earphones that play music 'via the magic of bone conduction' and often pitch them as this meaning you cannot damage your hearing from the music heard via them, usually backed up by some very woolly and often incorrect science. This is a meander through hearing via bone conduction and whether these products do what is claimed.
