Will I be Able to Hear Bone Conduction Headphones Even if I Wear Earplugs?

When we found this post we were so excited, having searched for over one year for this, discovering it on this website was an exciting time for me.

Hi Nick,

The short answer is yes, yes you can.

Because bone conduction bypasses the ear entirely and directly stimulates the ossicles (which is the scientific name for the tiny bones that reside in your inner ear, as well as the rationale behind comic book hero Daredevil’s athletic prowess), it is entirely possible to stick your ear plugs in and still listen to your ‘Bonephones’.

In some respects, it’s actually preferable. Y’see Nick, using headphones is fine and dandy, until you have to turn the volume all the way up in order to drown out noisy children, busy traffic and/or people shouting into their phones all around you. After that, if you increase the volume to too great a degree, you can expose your ears to sounds that can actually permanently damage your hearing.

Bone conduction, however, carries much less of a risk, because it does not effect the parts of the ear most at risk from loud noises.

Hearing is a process that actually has several stages. At first, your ear picks up sound waves, the sound waves pass into your middle ear (specifically, your auditory canal) before hitting the eardrum. The eardrum then vibrates, passing the sound down to the aforementioned ossicles (‘aforementioned ossicles’ is a lovely phrase, don’t you think?) From there, the ossicles transmit the sound to the cochlea, which is a fluid-filled structure that encodes the sound information in order for our brain to decode it (this is not unlike the way a wireless mouse works, actually).

Yup, the inner ear is a wacky world.

Essentially, bone conduction technology rattles the ossicles in the same way that they’d rattle in your inner ear, it just, to turn a phrase my father is particularly fond of ‘cuts out the middle man’. It really is an interesting invention.

So, as you see, there is no way a pair of earplugs pose any problem at all to your enjoying music or audio content on your Bonephones. I hope this helps. You’ll likely find this method especially useful if you happen to find yourself on a long plane journey and seated next to a disgruntled infant.

I’m actually fairly certain that bone conduction technology was invented during a similar scenario.

Have fun, Nick.

A two-way radio has to be able to work quickly and efficiently.

So i found this short article on the net and i understand that just posting it like a whole piece isn’t an excellent thing, I got permission from the original author and read up the way to curate content, so that is it…….i thought this was interesting because it highlights some of the highs and lows that I encountered when i was working in the business.

THE SPECS
The clarity of digital audio is undeniable. But if you still prefer analogue, then don’t despair. The DP 2400 is completely comfortable handling both analogue and digital signals.
But there’s a lot more it can do besides that.
The DP 2400 can even use its ‘IP Site Connect’ function to expand the capability of the device via the Internet. In addition, the ‘capacity plus’ function can use a single-site trunking system to enable over a thousand voice or data transfer-users without adding any new frequencies. It can even use an (optional) ‘linked capacity plus’ feature (a multi-site version of the ‘capacity plus’ function) that works in tandem with the IP functionality to ensure even broader fields of communication over greater distances.
There’s even an enhanced security function.
The Motorola DP 2400 comes in both VHF and UHF forms.
THE PRICE
At £284, this is a reasonably priced, yet high spec, device. With the release of the 3400, we can reasonably expect the price to drop a little more as well soon, but probably not by an incredible amount, as both models do seems to specialize in slightly different areas.
Overall, it does look like Motorola are offering a good radio-based product for your money, yet again.
THE PERFORMANCE
The design is hardy and utilitarian; this is the sort of two-way radio a security guard or professional soldier might use. Its tough, square edged and no-nonsense, but it still looks modern and professional. On top of this, the DP 2400’s ease of use makes the simplicity of the design a perfect marriage of model and operation.
As with most of Motorola’s designs, the DP 2400 is a tough little doohickey. The bodywork is so tightly sealed, in fact, that it is almost completely dust and sand proof and has a water protection rating of IP55 (that means you can use it in the rain, but you probably can’t take it snorkelling).
The audio performance of the DP 2400 is nothing short of spectacular. It even adjusts the levels to compensate for background noise automatically.
In fact, so high performance is this radio, that it actually meets US military standard 810 C D E F and G.
The only negative we could find was that the design was slightly bulky and the battery was a little heavy, however, the battery life is so good that we really don’t mind. Besides, it’s reassuring to be absolutely sure that you aren’t about to lose the product (you’d soon notice if you dropped it).
As an optional extra, you can even get a function that will interrupt an existing signal in order to deliver critical information without waiting for a line to close/open.
THE VERDICT
It really does seem as if Motorola have thought of everything this time around. What we’ve got here is a two-way radio that is pretty close to perfection. It seems to do anything you could possibly want it to and, when ‘pimped out’ with all the optional extras, it will surely do a lot more besides.
There aren’t really any downsides with this product, it works extremely well, is pretty much top of the line in its price range and is bang up to date technologically. What more can you ask for?
