Calling all car audio nerds!

Warning: This post could get very dull for those not working in automotive!

I have been working for the automotive industry on and off for almost a decade, and during this time I’ve had the opportunity to work with the big guys in France, Germany, UK, America, South America and China.

Each company has their own way of doing things and their own listening preferences, but we have made a set of mini guides to automotive audio processes.

  1. System Design
  1. System Tuning
  1. System Validation

If you are interested to learn more about these areas, please check out our automotive audio workshop. If your audio team needs support in any of these areas, please get in touch. We can assist in English or Mandarin.

Audiometry

How much do you know about your own hearing ability? An audiometry test is the most common way of measuring your hearing. In most countries, you can request one from your regular doctor, who will normally be able to do the test, and in other cases will refer you to an audiologist for the test. In this case, you will most likely have to pay something for the service. If you are serious about your ears, it is worth taking a test with a professional as they use high quality calibrated equipment. It should take no more than 20 minutes. The audiologist plays a series of tones and sounds and you must click a button when you hear the noise. This measures your threshold of hearing across the frequency range (from bass to treble).

If you don’t want to spend the time or money, why not take an online test at home? Of course online tests cannot be taken as 100% absolutely accurate due to the differences in your own test setup (which headphones etc), they will highlight any relative differences between left and right, and if you have a good pair of natural-sounding headphones, your test results should indicate your ability to hear across the frequency range.

For the unemployed/bedroom producers who have a bit more time on their hands, why not take several different online tests and study the results for similarities. Then, try the same test with 2 or 3 sets of headphones. If you see the same peaks and dips reappearing, then you can be sure that this is a true characteristic of your hearing and not due to your Beats headphones.

If you know your headphones don’t quite make the cut,

 

If you think you have a real problem with your hearing, book an appointment with your doctor to have it checked out properly, and make sure to protect those ears and prevent any further damage! You can read our guide to hearing protection here.

Look after those golden ears!

As the world around us gets louder and louder, so does the need to protect our ears and be aware of how much noise we are subjected to in our daily lives. As far as damage goes, you need to watch out for

  1. Very loud sounds like gunshots and explosions, even fireworks
  2. Moderately loud sounds over long periods, e.g. inside a factory or an all-night illegal warehouse rave

Don’t be a hero, save your ears! Or else you won’t be able to enjoy the wonders of sound in the Autumn of your life, like this guy…
