Scientific Societies Endorse Call for Study on Racism in Academia

Diversity Initiatives

Home » ASA Announcements

More than 70 scientific societies, including AIP, sent a letter to House Science Committee Chair Eddie Bernice Johnson (D-TX) last week expressing support for her recent request that the National Academies conduct a study on the “influence of systemic racism in academia.” Johnson has also sponsored an amendment to pending appropriations legislation that would allocate $1.5 million for the study. In endorsing her proposal, the societies wrote that the disproportionate rates of death and illness from COVID-19 among communities of color “illustrates with new urgency the need to foster a diverse and inclusive scientific workforce to tackle these and other challenges from a wider range of perspectives.” They added, “While efforts to increase diversity in the scientific workforce may have produced incremental change, we have yet to see large-scale results … We are hopeful that a comprehensive study by the National Academies will yield the data and tools that the academic community needs to pursue evidence-based changes leading to more rapid progress.”

House Committee on Science, Space, and Technology

Dear Chairwoman Johnson:

At this time of great challenges for our nation, we write to thank you for your leadership in confronting inequities in the U.S. scientific enterprise that have prevented full participation of racial and ethnic groups underrepresented in STEM. We therefore support your call for the National Academies of Science, Engineering, and Medicine (NASEM) to undertake a study to acknowledge and assess this structural problem, namely systemic racism in academia.

As we have seen in stark terms over the last six months, while the novel coronavirus is a threat to everyone living in the U.S., the burden has not been equally felt. There are disproportionately higher rates of illness and death in communities of color in the U.S. The reasons for this are many, but it illustrates with new urgency the need to foster a diverse and inclusive scientific workforce to tackle these and other challenges from a wider range of perspectives.

While efforts to increase diversity in the scientific workforce may have produced incremental change, we have yet to see large-scale results. Across disciplines, demographic representation throughout the ranks of academia still fails to reflect the diversity of our society. We are hopeful that a comprehensive study by the NASEM will yield the data and tools that the academic community needs to pursue evidence-based changes leading to more rapid progress.

A scientific enterprise that reflects the diversity of our nation will be more innovative and better equipped to address the challenges before us. Collectively, our organizations are working to change culture and improve diversity, equity and inclusion efforts within our staff, our members and our disciplines. The scientific community stands ready to work with you and your committee as you endeavor to address the systemic racism that exists within academia.

ASA Adopts Policy on Acoustic Hailing Devices

The ASA Executive Council adopted the following policy on Acoustic Hailing Devices on 10 July 2020.

ASA Policy Statement on Acoustic Hailing Devices

Acoustic hailing devices (AHDs), including Long Range Acoustic Devices (LRADs), were developed originally as military communication systems and are designed to project an intense, focused beam of acoustic energy over long ranges. As such, they are capable of delivering dangerously high sound levels (both verbal and siren-like signals) when employed at shorter ranges. In recent years, AHDs are used increasingly by law enforcement and related agencies to communicate with civilian populations at short ranges, for example, “crowd control” scenarios.

The Acoustical Society of America (ASA) recognizes potential risks to human health caused by AHDs, including permanent hearing loss and strongly urges:

  • Law enforcement agencies and organizations using or proposing to use AHDs for crowd control purposes to develop and adhere to strict safety guidelines on their use; these guidelines must prominently include limits on the level and duration of exposure to potentially traumatizing sounds consistent with established safety guidelines (e.g., NIH, CDC)
  • The establishment of rigorous training procedures for device operators
  • Funding of scientific research aimed at (a) assessing the level of risk associated with exposure to AHD signals, especially for vulnerable individuals, and (b) assessing levels within sound fields produced by AHDs in potentially untested settings such as highly reverberant urban environments

To ensure safe use of AHDs, the ASA further encourages the development of evidence-based policies on AHD usage by law enforcement and related agencies to protect targeted individuals, bystanders, and personnel from AHD-induced trauma, in addition to the implementation of procedures for monitoring and reporting AHD usage, and the establishment of public oversight, transparency and accountability mechanisms.

Recognizing the need to employ emerging technologies responsibly, the ASA recommends suspension of AHD use by law enforcement agencies for crowd-control purposes pending installation of safeguards to ensure the safety of the public.
