Anthropogenic noise exposure over development increases baseline auditory activity and decision-making time in adult crickets

Anthropogenic noise negatively affects some animals more so than others and often in different ways. Female crickets reared in traffic noise are reported to be faster or slower to locate male song than those reared in silence depending on species. No study has considered whether observed differences were due to hearing or decision-making. We reared female Teleogryllus oceanicus in traffic noise and silence, and adult females located male song broadcast amidst traffic noise or silence. We recorded activity of two auditory interneurons in a subset of individuals under identical acoustic conditions. Regardless of rearing treatment, crickets were slower to leave their shelter when presented with male song in silence than in traffic noise, while crickets reared in traffic noise were also slower to leave overall. Crickets reared in traffic noise also had higher baseline AN2 activity, but rearing condition did not affect hearing thresholds or auditory response to male song. Our results demonst..., Behaviour 
To compare the effect of the two rearing treatments on female phonotaxis, we randomly assigned crickets at fourteen days after final moult to a playback condition of either a traffic noise or silence (speaker on but no sound) during male song playback. In the center of the experimental trial room (H: 2.3 m, W: 2.6 m, L: 4.6m), we placed a circular arena made of cork (dia.: 1.22 m, 6.25 mm thick) on the floor, the arena was marked with a circle of 1.2 m diameter, and the circle divided into 8 segments of equal arc (45 degrees; Fig. 1B). We randomly assigned two focal speakers (Ultrasonic Dynamic Speakers, Vifa, Avisoft, Berlin) to opposite sides of the arena for each trial, positioned on the dividing line between two segments. Each focal speaker was flanked by two paired speakers (Companion, Bose) 25 cm to either side of it along the circumference of the arena. All speakers faced the center of the arena.
For each trial, we placed an adult female cricket under an egg cart..., , # Data from: Anthropogenic noise exposure over development increases baseline auditory activity and decision-making time in adult crickets

Dataset consists of behavioural and neuro-physiological data collected over the 2021 and 2022, using the cricket Teleogryllus oceanicus. 

## Description of the data and file structure

The data consists of several files. 

**2021_2022_T.oceanicus_experiment**: This file contains the behavioural data. It is organized with each row being an individual cricket, each given a letter + number code that indicates which rearing treatment they were in and the order they were put into the rearing chamber. Missing data represents values that were not recorded for various reasons (i.e. died before testing, pilot runs of the experiment, video file corruption, equipment failure). Signal location represents which position on the circular arena the mating song was being played from...,
