Subject: [AUDITORY] How to manipulate sound volume in Psychopy?

I struggle with findings online resources about sound volume manipulation in PsychoPy. I would be delighted if someone had answers to the following questions or could redirect me to online resources/tutorials/already made experiments.=20 ------=20 OS: Windows 10 PSYCHOPY VERSION: 2020.2.10 STANDARD STANDALONE?: yes=20 First issue:=20 I am designing a audiovisual experiment with the PsychoPy builder. I want to play sounds at a specific volume (attenuation) depending of the participant's hearing threshold in each ear. I understand how to set the volume parameter but I do not know if it is possible to set a different volume in each ear, especially for binaural sound stimuli.=20 One solution would be to have a monaural sound file for each ear and to play them simultaneously with different volume parameters but this solution seems clunky and I am afraid of timing issues.=20 Second issue:=20 I do not fully understand how to manipulate precisely sound intensity in PsychoPy. I understand that the volume can be determined with a value comprised between 0 and 1. Do you know to what this value corresponds? Moreover, how could I specify that a sound should be played _n_ decibels above a participant threshold?=20 ------=20 Thank you for your understanding. I prefer to use the Builder interface but I am open to resolve the problem through the Coder interface.=20 Best regards,=20 R=C3=A9my MASSON --=_8565d45dc1af5f66236dfcfd73a314f6 Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable <html><head><meta http-equiv=3D"Content-Type" content=3D"text/html; charset= =3DUTF-8" /></head><body style=3D'font-size: 10pt; font-family: Verdana,Gen= eva,sans-serif'> <p>Hello everyone,</p> <p>I am new to PsychoPy and I am trying to design an auditory task.
