(1) Free field to Eardrum Transfer Function (FETF) is one of the major factors influencing the identification of the sound source direction.

(2) The sound pressure at near distance under free field was computed by using the wave number integration and the basic characteristics of the radiated noise were analyzes.

(3) The source program is written in a free field format.

(4) A 1D finite element method in time domain is developed, where the wave motion of free field in elastic half-space by SH wave oblique incidence is simulated. Sentencedict.com

(5) The harder the soil is, the more similar the motion of foundation is to that of free field.

(6) Traditional anti-seismic design method all assumes that the ground is rigid and use the displacement of the free field as input ground motion for structure.

(7) The acoustic filed is calculated in different aspects, influence on the free field analyzed under different conditions, and useful conclusions obtained.

(8) The softer the soil is, the less the motion of foundation is than that of free field.

(9) In this paper, a closed chamber technique for measuring the complex free field sensitivity and directivity patterns of line array is described.

(10) In this paper, the propagation of train-induced vibrations and their influence rules in the surrounding free field and building are systematically analyzed.

(11) If the chin part is open you have a completely free field of view. The chin part has a solid locking in the top position.

(12) The ground reflection and attenuation must be properly accounted for in order to use the source spectrum measured at the site of the observer to predict the actual source spectrum in the free field.

(13) So the soil - structure interaction in the - rock foundation is different from that in the surface free field.

(14) The vertical motion at the top of hill is 40—125% larger than that on the ground of free field.

(15) The spectral component of foundation motion is changed, and the motion of foundation is smaller than that of free field.

(16) Head-Related Transfer Functions (HRTFs) are defined as the frequency responses from the sound source to both ears after filtered by the head, torso and pinna in the free field.

(17) In the first section, to study the acoustic response properties of the IC in the pipistrellus abramus, single unit extracellular recording with microelectrode was used in free field conditions.

(18) Two people walk on a cross - country slope built on a snow - free field in southeast Switzerland.
