11. Bats may detect acoustic signals from dish-shaped bracts such as those of " Marcgravia evenia ". 12. The photoacoustic immunoassay labels and detects target proteins using nanoparticles that can generate strong acoustic signals . 13. In a follow-up study, the researchers implanted tags in the cod that produced coded acoustic signals . 14. On the other hand, sound output may interfere with other acoustic signals , such as speech communication. 15. Its sinking resulted in three identifiable acoustic signals as compared to " Scorpion " s 15. 16. The timekeeper then immediately interrupts the game by sounding an acoustic signal and stops the time. 17. Analytic instruments such as the spectrum analyzer facilitate visualization and measurement of acoustic signals and their properties. 18. A transducer is a device that can transmit and receive acoustic signals ( " pings " ). 19. Acoustic signals from the accompanying research vessel guide SPURV in moving below the surface of the water.20. Therefore different ship classes will have different combinations of acoustic signals that together form a unique signature.
