Reverberation is defined as the <\/span>persistence of sound after its source has stopped making it. <\/b>This phenomenon it is caused by the reflection of sound on the different surfaces of a room, including walls, ceilings, floors, and furniture. these reflected sound waves make the sound energy persist, creating a reverberant sound. even the number of people present in a room affects reverberation. In an empty space, it will last longer compared to a space full of people.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Reverberation time: how is it measured?<\/span><\/h2>

It <\/span>is measured in seconds and is determined by the use of a sonometer (also known as sound level meter)<\/b>. This device measures the time gone by from the moment when the original sound source is halted until the intensity of the sound has decreased by 60 decibels (or 60 dBs). This method, known as RT60, was developed by <\/span>Wallace Clement Sabine<\/b>. For more specific and less invasive measurements, other methods such as RT30, RT20, RT15 or RT10 can be used, as they do not require reaching such loud levels of sound.<\/span><\/p>

Here at Mas Acoustics we provide <\/span>reverberation time measurement service<\/span><\/a> RT60 according to ISO 3382 ruling.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Difference between echo and reverberation<\/span><\/h2>

The main difference between echo and reverberation lies in the distance and perception of the reflected sound:<\/span><\/p>

  • Echo<\/b>: A reflected sound which is heard from over 17 meters away from its source location. It travels for 50 ms from its source to the listener and takes another 50 ms to return to its original point. At that point, it is perceived as a different sound from the original one.<\/span><\/li>
  • Reverberation<\/b>: It occurs when sound reflections arrive from less than 17 meters away, being perceived as the same sound as the one coming from its source location.<\/span><\/li><\/ul>

    Although both phenomena can happen in open and narrow spaces, echo is commonly associated with wide, open places and reverberation goes along with closed rooms.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

    Types of reverberation and their effects<\/span><\/h2>

    There are two kinds:<\/span><\/p>

    • Acoustic reverberation in a room<\/b>: It is produced by the reflection of sound in a room or exterior space. This type of reverberation must be regulated in conference rooms, classrooms, recording studios and concert halls, adjusting the reverberation time according to the needs of each space.<\/span><\/li>
    • Artificial or emulated reverb<\/b>: Used in recording studios and multimedia production. Known as \u201creverb\u201d, this technique modifies the sound of instruments and voices recorded in said studios with no reverberation with the use of electronic devices or emulation software to obtain a more organic sound. An example of artificial reverb would be the sympathizers that include a spring and its own regulator. For digital emulations, see the <\/span>Lexicon 224 Digital Reverb Plug-in<\/b>.<\/span><\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
