Late Night Listening

Pupshaw and Pushpaw agree! Musical and very resolving!

The Hegel HD20 DAC meets the CI Audio VHP•2 headphone amp. Listening to Bill Frisell’s My Buffalo Girl on a Macbook pro running iTunes/Pure Music with 64 bit math and power-of -two (88.2 Khz) upsampling. The CI Audio Transient MK II is providing the asynchronous USB-to-S/PDIF conversion, and the Hegel HD20 is doing the Digital-to-analog converting. The headphones in use are the classic Sennheiser HD-600 open ear cans. Stereo guitars, big bottom double bass, and the lovely B-3 organ carry you away – off to dream land…

Preventing Hearing Damage

Noise pollution is all around us, especially in the major cities of the world. experiencing this cacophony of sound is often disorienting and fatiguing. From the moment we step out our front door we are bombarded with a cluster of city sounds. Unlike our eyelids, we cannot close our ear canals with similar organs. Rather, we must voluntarily use a device that will reduce the passage of sound into the ear canal – earplugs. It makes you wonder if we had “earlids,” would our hearing be better?

Headphones/Earbuds

The use of portable music players/Ipods allows us to drown out the sounds of the city. These earbuds and headphones serve two purposes. First, they provide music reproduction for listening pleasure. Second, they passively (and sometimes actively) reduce sound from the surrounding environment. While reducing unwanted noises is welcome, directly injecting sound into your ear can pose some risks.

Although hi-fi speakers can be turned up to ear damaging levels, they have the advantage of not being strapped directly to your ear canal. Even more, speakers produce sound that travels through the air before it reaches your ears. Since air is an excellent absorber of sound, the overall sound pressure level will be reduced before it hits your ear drum. Private listening sessions on headphones and earbuds can be enjoyable, but you must excersice caution not to listen too loudly. A great article on “preventing hearing damage with headphones” can be found here.

Hearing Protection

Our hearing is an integral tool used for communication, balance, and localization. The human auditory system is truly remarkable and sensitive. An audiologist can advise you on hearing protection options to help maintain the longevity of your hearing.

Happy Listening!
