1.  The Right Ear is From Mars...  In a new study, scientists have found that the left and right ears process sound differently. From birth, the right ear responds more to speech , while the left ear is more attuned to music. The study could have substantial implications for deaf people who need cochlear hearing devices, which are implanted in only one ear. In other studies, researchers have found that children with hearing loss in the right ear tend to have more problems in school than children who are deaf in the left ear. In a followup letter, a chorus member reported that she was rehearsing the Verdi Requiem using a cassette tape with the full choral and orchestral accompaniment in the right ear and a piano line tapping out the notes for her part in the left ear. One time she inadvertently put on the headphones backwards and found the part more difficult to follow. Switching back made it more discernible and relaxing. NYT 14SE04

2.  An ad for Acoustiblok, an acoustic isolation material, looks interesting. It is a flexible sheet, weighing a pound per square foot, intended to installed in walls and floors, and claimed to have better isolation than 12" of concrete or a sheet of lead.
