3. Near Field
   Locations close to the sound source between the source and the far field. The near field is typically characterized by large sound pressure level variations with small changes in measurement position from the source.The sound pressure does not obey the inverse-square law and the particle velocity is...

4. Near Field - Close Field
   The area which is close to the source. If we take a mic and place it right up against a sound source, we will be picking up it's sounds as they are in the near field, and if we take the microphone and place it far away from the sound source, we would be picking up the sounds (so long as it isn't too...

6. Near-field
   (mathematics) In mathematics, a `near-field` is an algebraic structure similar to a division ring, except that it has only one of the two distributive laws. Alternatively, a near-field is a near-ring in which there is a multiplicative identity, and every non-zero element has a multiplicative ...
