With the information provided by you, we consult with our acoustical analyst to get you the exact amount of material you will need to add to your space. The steps to get this done are simple, all you need to do is: Measure your space and provide our team with the exact dimensions, ...
Sabine was asked to improve the acoustics of the main lecture hall in Harvard's Fogg Art Museum. He was first to measure reverberation time — which he found to be 5 1/2 seconds in the lecture hall. Experimenting first with seat cushions from a nearby theater, and later with other sound...
that can have a negative impact on speech intelligibility. Reverberation is the persistence of sound in a room once the sound signal has abruptly ceased. Reverberation time is the time in seconds that it takes for the sound to die down by 60 decibels or put another way to 1/1,000,000 of...
Installation requires a drill, Phillips-head screwdriver, tape measure and a hacksaw. Trim some wood off of the door or frame to make space, then screen the aluminum into place. The Quiet Door™ Perimeter Seal adapts to almost any door. 3. Fill the Space Under the Door The bottom of ...
You may also have been distracted by the constant hum of HVAC equipment. THX-certified auditoriums cannot exceed anoise criterialevel ofNC-30per octave. Noise criteria is a measure of background noise in a room -- in this case, noise from outside sources. NC-30 is comparable to the leve...
Professor Cox’s second test was designed to measure how well the screens achieve their main design goal: to prevent room reflections from the source being picked up by the microphone. This test also allowed us to measure the amount of unwanted coloration each screen introduced. ...
and is probably due to the fact that in the combined mix there is no one fixed reference point for the ear to measure changes in gain, making it far more tolerant of heavier compression — the same argument also applies to the effectiveness of multi‑band compressors. The main disadvantage...
The diffuse field correction curve illustrates the upper mid-frequency boost that occurs naturally to sounds when measured at the ear drum. If you were to measure the acoustic output from a flat measuring loudspeaker in anuntreated, reflective room at your eardrum, the response shape you would ge...
One detail on the spec sheet that you want to be sure to check is the ohms rating. Ohms are a unit of measure for the impedance or resistance in a piece of gear.To understand impedance, imagine a hose plugged up with gunk slowing the water flow. If you want more water to come out...
to place your desk there, but it will make your efforts to improve sound quality much more difficult. Instead, try moving your desk away and substituting a comfortable chair, perhaps topped with a cushion or throw for good measure. And don’t stop there - filling out your space with ...
