Recent experimental studies have indicated that injection molded 1–3 piezocomposite is suited for parametric mode sound generation. Using a new Navy calibration standard (F82), which relies on the 1–3 composite for the active layer, the authors w

A first projector that generates a beam of acoustic energy having a first equency, and a second acoustic projector that generates a beam of acoustic energy having a second frequency are provided. Interaction between the intersecting beams and particl

Intense low‐frequency sound can severely attenuate sound of higher frequencies through nonlinear interaction. On the other hand, intense high‐frequency sound does not appreciably alter a lower‐frequency sound field. An experiment is described w

An analysis is presented for a saturated parametric acoustic receiver that is based on the fact, first derived by Fenlon for low‐amplitude waves [J. Acoust. Soc. Am. 51, 284–289 (1972)], that saturation loss for the sum‐ and difference‐freque

A new type of parametric acoustic source configuration utilizes an endfire projector for the primary beam. This configuration shows promise for those applications requiring a projector having small frontal area, e.g., a source to be towed. A small en

A model is presented for predicting source levels and beam patterns generated by parametric acoustic sources of rectangular aperture. This model is a generalization of a previous model for square and circular apertures [J. Acoust. Soc. Am. 61, 325–

Experimental measurements of intensities and beam patterns of a parametric sonar transmitting array are presented. For a mean primary frequency of 720 kHz, secondary source levels up to 90 dB//1 μbar at 1 m were attained at 50 kHz. At this level, ho

A brief non-mathematical explanation of the difference frequency generation and beamforming process is followed by a step-by-step design procedure using the Mellen-Moffett parametric source model. The relative merits of projector feed with a single d
