Okay, let’s break it down. Jessica has a strong background in acoustics and audio engineering, which are in demand across various industries. Her skills in sound design and live sound engineering are also valuable. However, her proficiency in French is limited, which might affect her earning potential. Location is Santa Clara, California, which is a hub for tech and entertainment industries. According to national averages, acoustics professionals with similar skills can charge between $100-$200 per hour. Considering her experience and skills, I estimate her hourly rate to be around $125, which is on the lower end of the range. However, given her limited French proficiency, I've rounded down to $125.
