| If desired, the gradation of intensities here employed may be refined to the threshold of perceptibility, or beyond it. |
| Increasing the efficiency of transmission obviously goes much further than ensuring the perceptibility of the message. |
| But that thing of his dissembling was only subject to his perceptibility, not to his will determinate. |
| When evaluating a floor for vibration perceptibility, the designer should assume lower floor loadings than are required in designing for structural strength. |
| The perceptibility of social phenomena as such is conditional on the extent to which they impinge on the media. |
| More than half a century later, perceptibility remains an issue with physicists. |
