One of the most dramatic hormonal fluctuations occurs during pregnancy, and many professional singers have experienced difficulty singing while pregnant. However, scientists do not know if this effect is due to hormones or to some other cause, such as decreased lung capacity as the baby grows.
In order to assess the effect of hormones on a pregnant singer's voice, Filipa Lã of Aveiro University in Portugal followed a professionally-trained Portuguese singer through 12 weeks of pregnancy and for 12 weeks after birth. Once a week -- including just two days after the baby was born -- Lã recorded the singer reading and singing into a device that measures the pressure exerted to make each sound. Then Lã collaborated with Johan Sundberg of KTH in Stockholm, Sweden to reconcile the data with measurements of the singer's hormone levels. Their findings will be presented on Wednesday, October 28 at a meeting of the Acoustical Society of America (ASA) in San Antonio, TX.
This was the first longitudinal study of the effect of hormones on a singer's voice during pregnancy, and Lã and Sundberg found that the increased levels of hormones correlated with changes to the singer's vocal folds. Though temporary, the changes forced the singer to exert more pressure from her lungs to make the same notes.
"It seems that it's harder work during pregnancy to sing," says Lã. She adds, however, that this is preliminary research based on a single case study and that larger studies would be needed before doctors could give solid advice to professional singers.
The talk "Observations of the singing voice during pregnancy. A case study" (3aMU7) by Filipa Lã is at 11:15 a.m. on Wednesday, October 28.

WORLD WIDE PRESS ROOM
ASA's World Wide Press Room (www.acoustics.org/press) contains additional tips on dozens of newsworthy stories and lay-language papers, which are ~500-word summaries of presentations written by scientists for a general audience and accompanied by photos, audio, and video.
We will grant free registration to credentialed full-time journalists and professional freelance journalists working on assignment for major news outlets. If you are a reporter and would like to attend, please contact Jason Bardi (firstname.lastname@example.org, 301-209-3091), who can also help to set with setting up interviews and obtaining images, sound clips, or background information.
ABOUT THE ACOUSTICAL SOCIETY OF AMERICA
The Acoustical Society of America (ASA) is the premier international scientific society in acoustics devoted to the science of technology of sound. Its 7,500 members worldwide represent a broad spectrum of the study of acoustics. ASA publications include The Journal of the Acoustical Society of America (the world's leading journal on acoustics), Acoustics Today magazine, books and standards on acoustics. The society also holds two major scientific meetings each year. For more information about ASA, visit our website at http://asa.aip.org.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
