GRAZ, Austria--(BUSINESS WIRE)--Nov 7, 2024--
USound announced the results of a drop-test comparison between the company’s Conamara UA-C0503-3T tweeter and a standard balanced armature (BA) tweeter. Dropped on an asphalt concrete floor from a 150 cm height for 20 consecutive times, USound’s Conamara speakers remained unharmed, reaching a remarkable 100% survival rate.

Maintaining their total harmonic distortion (THD) and sound pressure level (SPL) results, the Conamara microspeakers were proven to be up to 25% more reliable than their competition. Under the same conditions, the BA tweeters exhibited a lower resonance frequency rate, noticeable SPL changes (+/- 7 kHz), while their THD limits were exceeded on at least two occasions. According to the results, the BA tweeters had a survival rate of 75% - 83% when measured on 100 mVrms and 200 mVrms data respectively.
“These results confirm that USound MEMS loudspeakers excel in both audio quality and durability, delivering a level of performance unmatched by traditional speakers. With significantly wider bandwidth, much lower Total Harmonic Distortion (THD), and 100% drop-proof reliability, our MEMS loudspeakers are the superior choice for next-generation wearables and hearables, setting new standards for audio clarity and reliability.”
– Ferruccio Bottoni, Co-founder & CEO of USound
Conducted for a product qualification in October, 2024, the unguided drop-test followed the IEC60068-2-31 environmental testing standards. The test results were evaluated using USound’s standard passing criteria for reliability tests. The two criteria state that, after the speakers are dropped, the sound pressure level (SPL) should not decrease or increase more than 3 dB, and that the increase of the total harmonic distortion (THD) must be below 5%.
The positive news follows another recent development: the ability to drive the Conamara MEMS speakers without DC bias, bringing a classic approach to speaker integration, while further decreasing power consumption.

Several large airstrikes hit Beirut’s southern suburbs early Thursday, including one on a site adjacent to Lebanon’s only international airport. The Israeli military had issued an evacuation notice for the site, saying there were Hezbollah facilities there, without giving more details.
Also Thursday, the Israeli military announced it expanded its month-old ground operation in northern Gaza to include part of Beit Lahiya, a town that has been heavily bombed since the earliest days of the war, where Israel says Hamas militants have regrouped.
Hezbollah leader Naim Kassem said in a speech aired Wednesday that the Lebanese militant group is open for cease-fire negotiations only once “the enemy stops its aggression.” His speech marked the 40-day mourning period since former Hezbollah chief Hassan Nasrallah was assassinated in Beirut.
Hezbollah began firing into Israel on Oct. 8, 2023, in solidarity with the Hamas militant group in the Gaza Strip. Since the conflict erupted, more than 3,000 people have been killed and some 13,600 wounded in Lebanon, the Health Ministry reported.
The Israel-Hamas war began after Palestinian militants stormed into Israel on Oct. 7, 2023, killing some 1,200 people — mostly civilians — and abducting 250 others. Israel's military response in Gaza has killed more than 43,000 people, Palestinian health officials say. They do not distinguish between civilians and combatants, but say more than half of those killed were women and children.
Here’s the latest:
JERUSALEM — Israel says it has reached an agreement to purchase 25 advanced F-15 fighter jets from U.S. aerospace giant Boeing for $5.2 billion.
The Defense Ministry said the agreement, concluded Wednesday, was part of a broader aid package approved by the U.S. government earlier this year. Deliveries will begin in 2031, and there’s an option for the purchase of an additional 25 aircraft.
The United States has provided crucial military support to Israel as it has battled Hamas in Gaza, Hezbollah in Lebanon and traded fire with Iran.
The Biden administration recently warned Israel that if it did not facilitate the delivery of more aid to Gaza, U.S. laws may force the administration to curb some of its military support.
The State Department said this week that Israel had yet to sufficiently improve aid deliveries ahead of a mid-November deadline.
President-elect Donald Trump has vowed to end the wars in the Middle East without saying how he plans to do it. He was a staunch supporter of Israel during his previous term but also cultivated close ties with Arab Gulf leaders.
RAMALLAH, West Bank — The Al Jazeera news network says the Israeli military has extended the order shutting down its bureau in the occupied West Bank.
Walid al-Omari, the network’s bureau chief, said Israeli troops raided the office in Ramallah again early Thursday and posted a notice extending the closure for an additional 45 days.
Israel had previously raided the office and shut it down on Sept. 22. Earlier this year, authorities took the rare step of barring the Qatar-based network from operating in Israel.
Israel accuses Al Jazeera of serving as a mouthpiece for Hamas, an allegation denied by the network. Last month, Israel accused six Al Jazeera journalists in Gaza of being Palestinian militants, which the network also denied.
Al-Jazeera has provided near 24-hour coverage from inside Gaza since the start of the Israel-Hamas war, with a heavy focus on the war’s toll among Palestinian civilians. Several of its correspondents have been killed or wounded by Israeli forces.
It also routinely airs unedited Hamas videos showing attacks on Israeli forces and hostages speaking under duress.
Israel’s parliament passed a law early Thursday that would allow it to deport family members of Palestinian attackers, including the country’s own citizens, to the war-ravaged Gaza Strip or other locations.
The law, which was championed by members of Prime Minister Benjamin Netanyahu’s Likud party and his far-right allies, passed with a 61-41 vote but is likely to be challenged in court.
It would apply to Palestinian citizens of Israel and residents of annexed east Jerusalem who knew about their family members’ attacks beforehand or who “express support or identification with the act of terrorism.”

JERUSALEM — The Israeli military has expanded its month-old ground operation in northern Gaza to a town that has been heavily bombed since the earliest days of the war.
The military said in a statement Thursday that “troops started to operate” in the area of Beit Lahiya after intelligence indicated the presence of militants there. Hamas has repeatedly regrouped in areas where the military already conducted major operations.
The town in the northwestern corner of Gaza was among the first targets of the ground invasion launched over a year ago, after Hamas’ attack into southern Israel. The northern third of the territory has been encircled by Israeli forces since then.
Israel launched another major offensive in nearby Jabaliya, a decades-old urban refugee camp, in early October. It has sharply restricted the amount of aid entering northern Gaza and ordered a full evacuation. Tens of thousands have fled to nearby Gaza City in the latest mass displacement of the war.
BEIRUT — Several large airstrikes hit Beirut’s southern suburbs early Thursday, including one on a site adjacent to Lebanon’s only international airport.
The Israeli military had earlier issued an evacuation notice for the site, saying that there were Hezbollah facilities there, without giving more details.
There were no immediate reports of casualties.
Beirut’s airport has not been directly targeted in the war between Israel and Hezbollah, and national air carrier Middle East Airlines has continued to operate commercial flights.
