Listed biotechnology firm Biotech Capital has invested $2 million in hearing technology company Sensear.
Following the deal, Biotech Capital will be the largest shareholder in the private company.
The $2 million investment was part of an overall $3 million funding round completed by Biotech Capital.
"The investment is consistent with previous shareholder communication in moving to reposition Biotech Capital's investment portfolio towards later stage companies either generating revenues or in human clinical trials," the company said in a statement.
Sensear's hearing technology has created hearing muffs and plugs that can be worn by people in noisy environments.
