Proposed transfer-function technique for earphone analysis by United States( Book )
4 editions published in 1985 in English and held by 11 libraries worldwide
This research was prompted by the need to select a suitable headset for auditory processing of passive-sonar information. The selection of an accurate transducer for auditory processing of passive sonar signals requires accurate measurement of frequency response. No standard for such measurement exists. The method proposed here uses a modified Zwislocki acoustic coupler mounted in an anthropometrically and acoustically average mannikin, KEMAR, in order to simulate the acoustic load that an average human ear would place on the earphone element. A computerized signal-collection and -analysis system substracted this transfer function from stored earphone-response data. Responses were averaged across samples of left and right earphone elements and across repeated measurements that sampled variability due to headset placement, seal around the ear, and headband tension. Analog plots of earphone frequency response were indistinguishable from computer regenerated plots of that same frequency response. Comparison of raw data and corrected data show the correction procedure to be within 0.2 dB of perect accuracy
Frequency response and distortion measurements of headsets for use in auditory sonar displays by United States( Book )
2 editions published in 1985 in English and held by 2 libraries worldwide
This research was prompted by the need to select a suitable headset for auditory processing of passive sonar information. Essential to making such selection is the accurate measurement of headphone frequency response as worn on the average listener. We evaluated 24 commercially available headsets for suitability in accurately presenting auditory sonar information. The evaluation employs a digitized transfer-function correction technique, which was developed in-house and reported in a previous paper. Eleven headset models exhibiting the most linear corrected frequency response 10 to 16 dB total variation were further evaluated for total harmonic distortion. All earphone measurements were made using a commercially available acoustic test mannikin containing an ear simulating coupler. This electroacoustic information is of value in sonar headset selection for optimal transfer of the acoustic signal to the listener. Keywords: Aural detection, and Distortion measurement

Growth of Hatchery-Reared Penaeus Aztecus on Experimental Diets by D Grajcer( Article )
1 edition published in 1972 in English and held by 1 library worldwide
During experimentation designed to determine the requirements for sexual maturation of brown shrimp (Penaeus aztecus) a series of diets were tested on juvenile and subadult shrimp. These diets were formulated from a series of compounds expected to provide the essential nutrients for growth and sexual maturation. Both natural and prepared foods (i.e., foods which have been processed for storage at room temperature) were tested. The ingredients of the foods tested and the processing methods used to stabilize the foods are described. Growth rates and amounts of food consumed for shrimp reared on these diets are discussed, and growth is compared with that observed for wild shrimp. Implications of these growth rates to shrimp cultures are discussed. Experimental stunting of juvenile shrimp was investigated as a means of storing excess animals temporarily
