PAST EXHIBITION

Sound Exhibition

 

 

This is a past exhibition.

Location:
Hall C, Science Centre

Typical time required:
30 - 60 min

 

Sound is all around us. It cannot be seen but can be felt  through vibrations. It warns us of danger, helps us navigate, entertains us and most importantly allows us to communicate by expressing ourselves audibly. Discover the surprisingly multifaceted phenomenon of sound as you engage with our range of fun and educationally stimulating exhibits.

Explore the science of sound by learning more about sound waves and how they are transmitted. Test your hearing range, learn how sound travels through your ears, be fooled by auditory illusions, and discover how music enriches our lives. Have fun experimenting with our musical exhibits and bring out the musician in you as you immerse yourself in the world of sound. Come explore the wonders of sound in this interactive exhibition.

Highlights

 

 

Sound Waves

Whether it is in a solid, liquid, or gas, sound travels in waves. These waves move by particles colliding with one another like a domino effect. Waves consist of collections of molecules moving back and forth together.

Learn more about sound waves and how sound propagates through our environment.

 

Resonance

Resonance is a common phenomenon that is particularly important for musical instruments. In fact, in many musical instruments, the part that first produces vibrations is often rather small – like a thin string of a violin. The largest part of the instrument –  like the curved, hollow body of the violin – is the main resonating part that amplifies and helps to determine many important aspects of the instrument's sound, including tone quality, timbre, and dynamic capabilities.

Find out more about objects that resonate and the sounds they make. Look out for the Hot Air Organ which uses heated air in a metal organ tube to produce sound.

 

 

 

 

 

Test Your Hearing

The sound frequencies audible to the human ear are usually between 20Hz to 20kHz. However, there can be considerable variations between individuals, especially at the high frequency range where a gradual decline with age is considered normal. Do you know your own hearing range? Test it out with the Hearing Range exhibit.

Having two ears (binaural hearing) helps us locate a sound’s origin. Do you know that sounds arrive slightly earlier and louder in one ear than in the other? These differences in volume and timing tell your brain where a sound comes from. Play with the Catch the Sound exhibit to find out more.

 

Listen!

Active listening is one of the elements of communication. We usually make sense of what is happening in our surroundings through both visual observations and active listening.

Can you listen to a conversation while you are talking? Do you think moods can be affected by music? Try some of the exhibits here and feel the effects yourself.

 

 

Sound Play 

Here’s your chance to play around and experience sound and music! Explore the Reactable that makes clever use of technology to create personalized music.

Watch out for amazing sand patterns created by a signal generator on a metal plate in the Dancing Sand exhibit.

Be mesmerized by the dancing iron fillings in the Metal Grass exhibit.  This exhibit offers a theatrical, lively and playful display of computer-controlled electromagnetism.

 

Sound Show 

The Sound Box at the back of the Sound exhibition is the venue for the Sound Show, conducted once or twice a day. Please refer to the Shows and Demonstrations page for show timings.
