Acoustics Today

This quarterly magazine contains tutorials, technical articles, ASA news, and more. The pieces in the magazine are aimed at people with a general background in acoustics, but might not be versed in the particular featured subject. Read about acoustics in past issues here.

Lay Language Papers

Lay language papers are short versions of papers and talks presented at Annual Meetings of the Acoustical Society of America. Please keep in mind that some of the research described in the lay papers may not have yet been peer reviewed. See all papers here.

Mothers and Their Children Hear a Musical Illusion in Strikingly Similar Ways

This paper reports new research indicating that a child’s perception of music may be influenced by the speech patterns of his or her mother. Previous findings by the author and colleagues had provided evidence that speech characteristics can have a strong influence on how we perceive music.

Modes of Vibration and Directivity of Percussion Instruments

When the membrane is struck, many different modes or patterns of vibrations are excited, including the six important ones […]. Each of these modes of vibration has its own pattern of radiation.

The Characteristics of Words that Lead to Malapropisms

One type of speech error currently under investigation is the malapropism. A malapropism is a whole word that supplants an intended word. (Other types of speech errors involve segments of sound supplanting intended sound segments). The words that are involved in malapropisms are related to each other in the way that they sound. However, the words that are involved in malapropisms are not related to each other in their meanings.

Acoustical Characterization of Straw Bales as Structural Elements

An understanding of the acoustical properties of straw bales is required if this medium is to be used appropriately. The transmission loss, a measure of how much sound energy is reduced in transmission through materials, was measured for a 20-inch-thick stuccoed wall of wheat and rye-grass straw bales. The effectiveness of straw bales to absorb sound was measured in an approximately cubical, ceramic-tiled room.

Time Reversal of Ultrasonic Waves in Solids

Acoustic Tim-Reversal-Mirrors (TRM) are, among many other applications, powerful instruments to detect defects in solid materials. Their ability to focus automatically on cracks makes them the most performant ultrasonic devices in this domain. In this paper, we prove that a simultaneous focalization of the different kinds of waves in the solid (transverse and longitudinal waves) can be obtained with such Time-Reversal-Mirrors.
