The Psychophysics Toolbox for MATLAB [58 (link)] was used to play sound waveforms. All stimuli were presented at 70 dB SPL with a sampling rate of 48 kHz in a soundproof booth (Industrial Acoustics). For experiments conducted at MIT, sounds were played from the sound card in a MacMini computer over Sennheiser HD280 PRO headphones. For experiments conducted at DTU, sounds were played from an RME FireFace UCX sound card over Sennheiser HD650 headphones.

The stimuli for all tasks were generated digitally by a personal computer, transformed by an audio interface (Syntax, FirefaceUCX), and presented through headphones (Sennheiser, HDA200). All participants were tested in the same order on the following tasks: ILD threshold measurement, ITD threshold measurement, and auditory filter measurement. A 2I-2AFC task with feedback was used for all measurements. In the ILD and ITD threshold measurements, participants were required to indicate the laterality of the stimulus in the second interval relative to that in the first interval. In the auditory filter measurement, participants indicated the interval containing the pure-tone signal. Participants used a computer mouse and reported the answer by selecting from choices displayed on a computer monitor. All participants were given a couple of practice runs prior to data collection and were checked whether they could understand the tasks.

Seven Japanese speakers (5 males and 2 females) participated in this experiment. All participants had normal hearing (hearing levels were below 12 dB in the frequency range from 125 to 8,000 Hz).
All NVS stimuli were randomly presented to both ears of a participant through a PC, audio interface (RME, Fireface UCX), and headphones (SENNHEISER HDA 200) in a sound-proof room. The sound-pressure levels of background noise were lower than 25.8 dB. The soundpressure levels of the output from the headphones were calibrated to a comfortable level (about 65 dB) by using a head and torso simulator (B&K, type 4128) and soundlevel meter (B&K type 2231). There were 20 trials in a session (2 familiarities  10 words  6 conditions). The words for all trials were different. Participants were asked to input a word of four morae as they understood it by using a keyboard. Each stimulus was presented only once.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
