When music is played with a lot of sustained notes, then longer reverberation times are required. Symphonic musicĪs can be seen, when speech is involved, the reverberation time needs to be less. Here are some optimal or preferred reverberation times (in seconds) for various types of music and speech. In the app world, this measure is frequently referred to as the Energy Time Curve because it shows the energy drop off as a function of time (in seconds). Reverberation times have been used since 1900 with the construction of the Boston Symphony Hall. Reverberation time is the amount of time (in seconds) for a sound to die off to a point that is 60 dB below the initial time. Too short of a reverberation time and the room sounds sterile- time to pull back the curtains and remove some rugs. Having a reverberation time that is too long will muddy up the sound and this would call for absorptive curtains, floor and ceiling coverings to reduce the echoes.
This can be your home studio/garage, a high school band room, or a professional venue. Sound level meters and reverberation time measures are not just useful in classrooms, but in a wide variety of musical and music settings. Similar apps are available from other suppliers but by in large, are quite similar. Just go to the apple app store or to to see what they have.
The same thing was found for reverberation time. In most cases, the sound level meter app was within 1 dB of the more expensive type II sound level meter. It seemed that these apps did as well as the very expensive ones and were obviously more portable, and accessible. Joe gave a talk at last year’s American Academy of Audiology conference in Chicago where he compared some of the inexpensive apps (or is it aps?) that can be downloaded onto your iphone or ipad against expensive sound level meters and devices to measure the reverberation time in a room.
So, I can’t give you the full title, but trust me, it’s a great book… I guess that’s why someone permanently borrowed it?īut back to Joe…. Normally I would simply reach up and pull it off my bookshelf, but alas, someone has “permanently borrowed” my copy. Carol Flexer and Carl Crandell wrote the seminal book on room acoustics for hard of hearing children. For those of you who don’t know Joe, think “room acoustics”. Joe Smaldino put me on to some apps that can be downloaded onto your iPhone, iPod touch, or iPad.
