The sneng or snaeng (Khmer: ស្នែង, "horn") is an aerophone made from an ox horn or water buffalo horn. It is loud enough to call across a distance and has been used in rural environments to signal mealtimes, give warning, call for help or indicate a need to return to the village. It was also used to call domestic elephants in from the field, and hunters communicated with it.^[1]

Two different types of sneng exist:

• The more common one is a side-blown instrument with a rectangular hole on the side of the horn, where a bamboo single-free-reed mouthpiece is fastened with wax.^[1][2] The reed there can be either blown or sucked to produce a tone.^[1] Both ends of the horn are open and function as finger holes to change the pitch,^[1] the pointed end covered by the left index finger and the wide end covered by the right palm.^[2] This type is capable of two notes, tuned a fourth apart.^[1]
• Another type is an end-blown instrument with the tip of the horn cut off and without the bamboo mouthpiece, like the conventional blowing horn. It is less common because it produces only one note.^[2]
