Numerical & Room Acoustics Simulation (internship)

Job description

About

Echo Silence is a Paris-based DeepTech startup developing acoustic metamaterial solutions for advanced industrial noise control. Our technologies target acoustics noise from fans, ducts, HVAC systems, and industrial equipment, combining numerical modeling, experimental validation, and scalable design. The company is supported by leading European innovation programs and works closely with industrial partners in energy, mobility, and infrastructure.

Job Description

We are seeking a motivated intern to contribute to our numerical and experimental acoustics activities, with a focus on room acoustics modeling, simulation, and optimization. The intern will play an active role in developing simulation models that support the design and validation of our next-generation acoustic solutions.

Key Responsibilities:

· 
Conduct numerical simulations using COMSOL Multiphysics to optimize material geometry and acoustic performance.

· 
Model and analyze room acoustics to enhance noise reduction and insertion loss.

· 
Participate in experimental validation of numerical results using laboratory setups.

· 
Support proof-of-concept (PoC) studies and product development initiatives.

· 
Document findings and present results to the R&D and product teams.

Internship Details:

· 
Location: Champs-Sur-Marne (Hybrid / On-site)

· 
Duration: 6 months (flexible start date)

· 
Compensation: Paid internship

Preferred Experience

· 
Education: Master 1 or Master 2 in Acoustics, Mechanical Engineering, Physics, or related field.

· 
Technical Skills:
