Hung gongs are usually played with soft mallets to give loud, resonant sounds with a gentle
timbre . Kettle-gongs are usually played with wooden sticks, giving a hollowed, ringing sound. Large gongs are often imported from Java, which has a tradition of making very high-quality gongs, rather than being part of the set of instruments created and tuned to be played together.
Keyed percussion
Typical gender metallophone
Metal keys are strung in a row, suspended so that they can vibrate freely. A bamboo tube under each key is tuned to resonate at its pitch. The wooden frame of the instrument is often elaborately carved and painted.
The characteristic sound of many popular kinds of
gamelan is provided by metallophones. A
metallophone is a
percussion instrument consisting of a row of metal bars (
keys , like the keys of a piano); each key gives a specific
pitch when struck. The number of keys depends on the type of instrument and the
scale used by the ensemble. Some have as few as four keys; others may have a dozen or more.
Metallophones
The characteristic sound of many
gamelan is provided by metallophones. High-pitched instruments played with hard mallets (on left) have a very bright timbre, while lower-pitched instruments played with soft mallets (on right) have a gentler, more resonant timbre. (
UIUC Fall 2007 gong kebyar class. )
The keys of some metallophones are typically struck with small wooden hammer-like mallets, and the
gamelan that feature these instruments tend to have a very bright, very loud sound. Others (particularly the lower-pitched metallophones in an ensemble) are usually struck with a softer, padded mallet. The playing technique for both usually involves striking the keys with the mallet held in one hand, while the other hand is used to stop keys from ringing too long (by touching them firmly, which stops their vibrations). See
below for more detailed descriptions of a few specific metallophones.
Some
gamelan instruments are in the
xylophone family; these are similar to metallophones, but their keys are made of wood or bamboo. These quieter instruments were not part of the court-music tradition, so they have strong associations with relaxed, informal music-making.
Balinese keyed percussion fall into two broad categories,
gender and
saron . In
gender instruments, each key is suspended (by cords) over its own bamboo-tube
resonator , which is carefully tuned to resonate at the pitch of that key. In
saron instruments, all of the keys are suspended over a single trough-shaped resonator.
Saron -family instruments are much less common on Bali than on Java.
There are many different Balinese keyed percussion instruments, particularly in the
gender family. They are named according to the type of
gamelan they play in, their mallet type, and their
register (pitch range). See
Ensembles for an idea of the variety of keyed percussion that can be present even in a single
gamelan .

you have been hired as an espert witness in a court case involving an automobile accident. the accident involved car A of mass 1500kg which crashed into stationary car B of mass 1100kg. the driver of car A applied his brakes 15 m before he skidded and crashed into car B. after the collision, car A s
can someone explain to me, an ignorant high school student, why the trend of the graph doesn't follow the fact that the higher frequency a sound wave is, the more power it is, hence, making me think the phons output would follow this general trend?
Nevermind i just realied that the graph is the phons output for a person with normal hearing and not just the phons output of the sound waves power, I should read the entire thing next time
Joseph
Follow up question, does anyone know where I can find a graph that accuretly depicts the actual relative "power" output of sound over its frequency instead of just humans hearing
