What is Sound? - Sophie Jung
The sonic explorers workshops will be assisted by Sophie Jung, a talented music technology student from the Queensland Conservatorium of Music in Brisbane. Sophie is an aspiring sound artist & composer and has written an introduction article to sound for the sonic explorers blog:
“Sounds are pressure waves travelling through a medium like air and water. If there is air, sounds are ‘here, there and everywhere’ with or without our consciousness. Sounds generally are characterized by pitch, loudness and timbre. For pitch, humans normally can perceive from the lowest of 20 Hz to the highest of 20 kHz frequencies. The ultrasounds above 20 kHz are inaudible to humans, however, some animals like bats and dolphins can even use them. I particularly prefer low frequencies like bass sounds, which are sometimes more felt than heard. Interestingly, babies feel comfortable when they hear the low sounds from a vacuum cleaner, because it reminds them of the time and place when they were in their mother’s womb. If a sound source increases in loudness, it is perceived as approaching. Changing the amplitude of a sound source is a simple but effective way in a sound production process to differentiate the distances of the sound sources. Also, reverberation, the ratio of direct to reflected sound, is an important factor related to the space that the sound is in. When we hear a sound, the particular place such as a living room, bath room, train or on the street will affect this. We can also comprehend that some sounds are dark or warm, while other sounds are bright, harsh or mellow. These are examples of the timbral characteristics of sounds.
I think it is important for young people to explore the sound world. If they take time to actively listen to the sounds around them, they will be surprised by the variety of sounds and the different sound characteristics. It will be meaningful for young people to take the opportunity to engage in sound workshops, which can help them to learn how to appreciate the various qualities of sounds. To experience the sonic world around them can also be a good part of their emotional development.
Before I began to study music technology at the Conservatorium, I wanted to know more about the techniques of how to manipulate sounds for my music compositions. Through the recording and mixing experiences, I have gained very practical knowledge of how to control the sounds that I work with. The technology gives me wings to create new sounds using the existing sounds, and they help me to find continuous joy while I create my compositions. If a sound is an egg, with technologies and your preferences, you can scramble, boil, or fry it, or even make a pavlova.”
world listening day 2012
The 2012 World Listening Day happens on Wednesday, July 18th. The purposes of World Listening Day are:
- to celebrate different ways we can focus on our soundscape (sonic environment);
- to raise awareness about the acoustic ecology movement, including ideas regarding how noise pollution can be reduced; and
- to introduce new educational initiatives and community events related to listening and acoustic ecology.
Participation in the 2012 World Listening Day focuses on the aforementioned goals, which could include listening parties, listening to one’s soundscape in private, private or public soundwalks, public forums about acoustic ecology, and more. What would you like to do on the 2012 World Listening Day? Events could happen on Wednesday, July 18th. However, if another day during that week (July 15-21) would work better with your schedule, that would be fine.
World Listening Day happens annually on July 18th—the birthdate of R. Murray Schafer, a Canadian composer who established the World Soundscape Project. Its research laid the foundations for what became known as Soundscape Studies and Acoustic Ecology.
Dozens of organizations and more than a thousand people from six continents have participated in World Listening Day so far — on the inaugural World Listening Day in 2010, and the second WLD last year. Both were great successes, and we’re hoping to have more people and organizations participate this year. Please fill out this 2012 World Listening Day participation form and return it to firstname.lastname@example.org, with “World Listening Day” in the subject line if you are interested in participating.
TreeSongs: Transient Sound Installation
2pm – 4pm – July 1st, Maroochy Botanic Gardens, Sunshine Coast, Queensland
TreeSongs is an evocative transient sound installation featuring live performances and ephemeral soundscapes planted on portable speakers in the natural environment.
The audience will be guided through the installation in small groups experiencing a curated selection of outcomes from the Sonic Explorers workshops, a dynamic series of activities involving Soundscape Ecology, recording experiments and sound sculpting in the natural environment.
This immersive experience ignites the auditory perception and constructs a new world shaped by sound and navigated by listening. TreeSongs encourages a greater awareness of the constant soundscape that surrounds us at a time when it is increasingly important to listen to the natural environment.
The TreeSongs experience lasts for 15mins and will run 6 times from 2pm-4pm on July 1st at the Maroochy Botanic Gardens on the Sunshine Coast as part of Treeline 2012 www.treeline.org.au
