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 (email@example.com, 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.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
