A duo of undergraduates at George Mason University in Virginia created a device that they say puts out fires with a pretty daft bass tone.

How sound affects the taste of our food
High-frequency sounds enhance the sweetness in food, while low frequencies bring out the bitterness. So could sound replace sugar? And what kind of music should restaurants play? [Read more]

Hearing under water…

Do we hear better under water?

Yes and no.

The detection of sound waves actually works better in water than in air because water transmits pressure waves more efficiently.

However, the difference in density means that human speech sounds are muffled or garbled underwater, making talking across a distance practically impossible. This is why scuba divers communicate by hand signals.

Underwater sound systems:
We evolved to process sound data on land, so we simply don’t hear as well at the bottom of a river — despite the ability of some divers to have ultrasonic hearing underwater. When you’re underwater, however, flooding in the outer ear prevents a lot of that necessary vibration and essentially nullifies your air conductivity hearing ability. We call this bone conductivity, the conduction of sound to the inner ear through the bones of the skull. This mode of hearing is 40 percent less effective than air conductivity, but it’s still the primary way we hear underwater [source: NOAA].

Unity Audio Time Saver: changing import settings for multiple audio files

Edit: Unity5 supports changing multiple settings, so this post becomes obsolete!

Multiple-object editing not supported.

Multiple-object editing not supported. RSI!

Ever wondered why it’s not possible in Unity3d to change the sound settings of multiple sound assets at the same time? Unlike other importers, you get the “multiple-object editing not supported” notification if you try to do this.
Recently I came across this forum post outlaying a script that allows you to select various sound assets and apply the same setting for all selected files. So now you can toggle 100 sound files to 2d mode instead of 3d without mindlessly pressing that apply button 100 times!

PhD Thesis Captivating Sound: the Role of Audio for Immersion in Games

PhD award

PhD award

The word is out: I hereby present you my PhD thesis! After the final writeup in 2009, it took some time to get my viva arranged in August 2010. Sorry to keep you waiting…but now, it can be downloaded via this blog.

This thesis addresses the role of audio for immersion. Yep, the I-word…almost just as Impossible as it is Irresistible to designers. Yet, I’ve tried to come up with some useful theory for those who want to know more about the design of sound, music and speech in games and the conceptual decisions that are involved.
