This NASA video segment explores how different frequencies of sound travel. The segment is part of the NASA SCIFiles program, which features the Tree House Detectives, a group of young students who work together to solve everyday problems. In this segment, the detectives gather information about sound to hypothesize why dogs are barking throughout their town. The detectives and neighborhood scientist, Dr. D., perform a demonstration that shows that higher-frequency sounds are easier to block than low-frequency sounds.
