|
 | Using sketches of nine present and futuristic helmet forms, a survey was conducted to develop techniques to evaluate a user population's esthetic preferences for military helmets. The results showed that the M1 helmet had a high level of acceptance based on esthetic qualities. It was concluded that it is possible to find regularities in esthetic preference and that the M1 helmet can be used as a suitable reference style. An ... |

|
| Thirty-eight enlisted men, 18 ordnance and 20 infantrymen, judged whether experimentally weighted helmets were heavier, lighter or the same weight as the reference M1 helmet. The findings indicate a lower difference threshold of 2.0 pounds and an upper difference threshold of 3.85 pounds for the combined groups. The ordnance group's lower difference threshold was 2.25 pounds, while the Infantry group's lower threshold was 1.8 pounds. The upper threshold for the ... |

|
| Audiometric threholds were determined for 12 subjects under three head conditions: bareheaded, while wearing an M1 helmet, and wearing an experimental helmet. The thresholds were measured for seven tones: 125, 250, 500, 1000, 2000, 4000 and 8000 Hz, at each of five angular orientations. Statistically noteworthy differences were studied for main effects and interactions. These appear to fall within the range of variation most people ordinarily experience on a day-to-day ... |

| Authors:
David J. Florip; Robert W. Bauer; HUMAN ENGINEERING LABS ABERDEEN PROVING GROUND MD
|
| Recovery of complete dark adaptation was observed after exposure to single pulses of light. Illuminances were measured at the subject's face, and durations ranged from 0.01 to 1.0 second. Subjects recorded their own recovery by adjusting an adaptometer to the lowest luminance detectable. Recovery times were sensitive to both duration and illuminance but varied most predictably with total light flux as measured in lumen-seconds. (Author) |

|
| The state of the art in noise-exposure criteria is reviewed and it is suggested that such criteria are in need of revision and extension to meet future operational requirements of the Army. Further, existing noise criteria, expressed in terms of 'decibels of hearing loss,' should be re-stated in terms of predictions about the performance of military personnel after they have been exposed to noise. Such re-statement in performance terms will ... |

| Temporary threshold shifts were determined for single exposures of subjects to impulses produced by the M20A1 and the M72 rocket launchers. These exposures were at levels up to 179 dB without hearing protection, and up to 184 dB with hearing protection. This study indicates that the CHABA impulse noise damage-risk criterion is valid for single impulses having durations of 12 to 34 milliseconds. The firer of the M72 is subjected ... |

| An analysis of variance program for small disk-supported computers was developed on an IBM 1130, 8K core and one-disk drive. This program will accept balanced analyses containing as many as eight factors in any combination of within- and between-subject effects. The number of levels of any factor is restricted only by the number of data points. On an 8K, IBM 1130, the program will accept 2050 floating-point or 4100 integer ... |

| Determining the requirements of helicopter lighting requires selecting the major factors that contribute to the lighting power of a surface light source. Since the light source must be functional, sky brightness, atmospheric attenuation and other characteristics of light sources such as size, shape and angular velocity must be studied. The report presents a model that looks at each of these variables separately. More investigation is needed in the field of ... |

| Sixteen observers adjusted the position of white or colored rod until it seemed to be alongside a reference white or colored rod. The colors used were blue and red of matched luminances. Observers tended to see the red rods as nearer and the blue rods as further away. It was concluded that red and blue are used as cues for depth perception. (Author) |

In adulthood they were exposed for three minutes to a large open field for one, two, three or four days. Fifteen minutes after the last exposure they were sacrificed and free plasma corticosterone was assayed. Handled subjects showed a significantly lower adrenocortical response to the open field than non-handled subjects. This finding supports the previously ... |

| Using the method of pair comparisons, subjects judged 12 stimulus configurations comprised of horizontal Mueller-Lyer (M-L) figures bordered above and below by shorter or longer anchoring lines. From the pooling model of adaptation-level theory, it was predicted that perceived length of the M-L figures would be assimilated toward anchor length. Results confirmed the prediction. (Author) |

| Two experiments are reported in which a visual stimulus of one hue was paired with two lighter weights and a stimulus of a different hue was paired with two heavier weights. The purpose of the experiments was to determine whether these visual stimuli would be effective in distorting the judgments of the heaviness of a single weight lying midway between the lighter and heavier weights.

The results were interpreted as supporting Miller's coding hypothesis about superordinate and subordinate labels. The nature of the categorization was not found to be exclusively organizational or associational. A relationship between organization and amount ... |

| The development of modern weapons and related training devices often results in the production of man-machine systems in which the human must operate controls in response to information obtained through visual and auditory channels. The human operator is placed in many military situations where sensory interactions can occur between the visual and auditory systems, since an operator must simultaneously monitor a visual display and listen to one or more incoming ... |

| Comparisons were made between plain instrument cover glass used on aircraft instrument panels and cover glass deposited with multilayer antireflection coating conforming to MIL-C-14806 and AMS 2521. Photometric measurements of reflections, light transmission and contrast indicated the effectiveness of the reflection-reducing coating. Reflected glare from the face of instruments was significantly reduced by the reflection-reducing coating and increased light transmission enhanced contrast on instrument dial faces. (Author) |
