This noun denotes sound or resonance, appearing in Psalm 150's crescendo of praise. The context pairs it with 'cymbals of sound' parallel to 'cymbals of shouting,' suggesting either resounding or ringing quality. The term comes from the root 'to hear,' so it describes audible quality—something meant to be heard. In worship, such sound carried meaning beyond mere noise; it proclaimed God's glory. The psalm's climactic call to praise Him with instruments that produce sound reflects Israel's theology that creation's purpose is to make God's glory audible, filling heaven and earth with praise.
