| 31. | A microphone is distinguishable by the voltage value produced when a known, constant sound pressure is applied.
|
| 32. | Interaural level differences ( ILD ) represents the difference in sound pressure level reaching the two ears.
|
| 33. | In addition, microphones are not uniformly sensitive to sound pressure, and can accept differing levels without distorting.
|
| 34. | A p-u type of sound intensity probe measured both the sound pressure and the particle velocity directly.
|
| 35. | Additionally, discharge of firearms in indoor ranges can produce noise levels of over 140 dB sound pressure level.
|
| 36. | Some phenomena linked to frequency of the sound pressure field lead to poor homogeneity of a pressure field.
|
| 37. | In PCM, each audio sample describes the sound pressure at an instant in time with a limited precision.
|
| 38. | The outer ear funnels sound vibrations to the eardrum, increasing the sound pressure in the middle frequency range.
|
| 39. | Measured sound pressure was between 29 and 32dBA in idle mode and 31 to 34dBA during seek mode.
|
| 40. | Ears detect changes in sound pressure.
